High-Linearity, 1700MHz to 3000MHz Upconversion/
Downconversion Mixer with LO Buffer/Switch
The MAX2041 high-linearity passive upconverter or
downconverter mixer is designed to provide 7.4dB NF
and a 7.2dB conversion loss for an RF frequency range
of 1700MHz to 3000MHz to support UMTS/WCDMA,
DCS, PCS, and WiMAX base-station transmitter or
receiver applications. The IIP3 is typically +33.5dBm
for both downconversion and upconversion operation.
With an LO frequency range of 1900MHz to 3000MHz,
this particular mixer is ideal for high-side LO injection
architectures. (For a pin-compatible mixer meant for
low-side LO injection, refer to the MAX2039.)
In addition to offering excellent linearity and noise performance, the MAX2041 also yields a high level of component integration. This device includes a double-balanced
passive mixer core, a dual-input LO selectable switch,
and an LO buffer. On-chip baluns are also integrated to
allow for a single-ended RF input for downconversion (or
RF output for upconversion), and single-ended LO inputs.
The MAX2041 requires a nominal LO drive of 0dBm, and
supply current is guaranteed to be below 145mA.
The MAX2041 is pin compatible with the MAX2031
815MHz to 995MHz mixer, making this family of passive
upconverters and downconverters ideal for applications
where a common PC board layout is used for both frequency bands.
The MAX2041 is available in a compact 20-pin thin
QFN package (5mm x 5mm) with an exposed paddle.
Electrical performance is guaranteed over the extended
-40°C to +85°C temperature range.

Note 1: All limits include external component losses. Output measurements taken at IF port for downconverter and RF port for
upconverter from the Typical Application Circuit.
Note 2: Compression point characterized. It is advisable not to continuously operate the mixer RF or IF input above +15dBm.
Note 3: Measured with external LO source noise filtered so the noise floor is -174dBm/Hz. This specification reflects the effects of all
SNR degradations in the mixer, including the LO noise as defined in Maxim Application Note 2021.
Note 4: Refer to the MAX2043 for improved LO leakage of -52dBm typical.

Detailed Description
The MAX2041 can operate either as a downconverter
or an upconverter mixer that provides 7.2dB of conversion loss with a typical 7.4dB noise figure. IIP3 is
+33.5dBm for both upconversion and downconversion
operation. The integrated baluns and matching circuitry
allow for 50Ω single-ended interfaces to the RF port
and two LO ports. The RF port can be used as an input
for downconversion or an output for upconversion. A
single-pole, double-throw (SPDT) switch provides 50ns
switching time between the two LO inputs with 43dB of
LO-to-LO isolation. Furthermore, the integrated LO
buffer provides a high drive level to the mixer core,
reducing the LO drive required at the MAX2041’s
inputs to a range of -3dBm to +3dBm. The IF port incorporates a differential output for downconversion, which
is ideal for providing enhanced IIP2 performance. For
upconversion, the IF port is a differential input.
Specifications are guaranteed over broad frequency
ranges to allow for use in UMTS, cdma2000, 2G/2.5G/3G
DCS 1800, PCS 1900, and WiMAX base stations. The
MAX2041 is specified to operate over an RF frequency
range of 1700MHz to 3000MHz, an LO frequency range
of 1900MHz to 3000MHz, and an IF frequency range of
DC to 350MHz. Operation beyond these ranges is possible; see the Typical Operating Characteristics for
additional details.
12
This device can operate equally well in low-side LO injection applications as long as the LO frequency range is
between 1900MHz and 3000MHz. If an LO frequency
range below 1900MHz is desired, refer to the MAX2039.
RF Port and Balun
For using the MAX2041 as a downconverter, the RF input
is internally matched to 50Ω, requiring no external matching components. A DC-blocking capacitor is required
since the input is internally DC shorted to ground through
the on-chip balun. The RF return loss is typically better
than 17dB over a 1400MHz to 3000MHz frequency range.
For upconverter operation, the RF port is a single-ended
output similarly matched to 50Ω.
LO Inputs, Buffer, and Balun
The MAX2041 can be used for either high-side or lowside injection applications with a 1900MHz to 3000MHz
LO frequency range. For a device with a 1500MHz to
2000MHz LO frequency range, refer to the MAX2039
data sheet. As an added feature, the MAX2041 includes
an internal LO SPDT switch that can be used for frequency-hopping applications. The switch selects one of the
two single-ended LO ports, allowing the external oscillator
to settle on a particular frequency before it is switched in.
LO switching time is typically less than 50ns, which is
more than adequate for virtually all GSM applications. If
frequency hopping is not employed, set the switch to
either of the LO inputs. The switch is controlled by a
digital input (LOSEL): logic-high selects LO2, logic-low
selects LO1. To avoid damage to the part, voltage MUST

High-Linearity, 1700MHz to 3000MHz Upconversion/
Downconversion Mixer with LO Buffer/Switch
High-Linearity Mixer
The core of the MAX2041 is a double-balanced, highperformance passive mixer. Exceptional linearity is provided by the large LO swing from the on-chip LO buffer.
Differential IF
The MAX2041 mixer has an IF frequency range of DC to
350MHz. Note that these differential ports are ideal for
providing enhanced IIP2 performance. Single-ended IF
applications require a 1:1 balun to transform the 50Ω differential IF impedance to a 50Ω single-ended system.
After the balun, the IF return loss is better than 15dB.
The differential IF is used as an input port for upconverter operation. The user can use a differential IF amplifier
following the mixer but a DC block is required on both IF
pins. In this configuration, the IF+ and IF- pins need to
be returned to ground through a high resistance (about
1kΩ). This ground return can also be accomplished by
grounding the RF TAP (pin 3) and AC-coupling the IF+
and IF- ports (pins 19 and 18).
Layout Considerations
A properly designed PC board is an essential part of
any RF/microwave circuit. Keep RF signal lines as short
as possible to reduce losses, radiation, and inductance. For the best performance, route the ground pin
traces directly to the exposed pad under the package.
The PC board exposed pad MUST be connected to the
ground plane of the PC board. It is suggested that multiple vias be used to connect this pad to the lower-level
ground planes. This method provides a good RF/thermal conduction path for the device. Solder the exposed
pad on the bottom of the device package to the PC
board. The MAX2041 Evaluation Kit can be used as a
reference for board layout. Gerber files are available
upon request at www.maxim-ic.com.
Power-Supply Bypassing
Proper voltage-supply bypassing is essential for highfrequency circuit stability. Bypass each VCC pin and
TAP with the capacitors shown in the Typical
Application Circuit; see Table 1. Place the TAP bypass
capacitor to ground within 100 mils of the TAP pin.

The RF and LO inputs are internally matched to 50Ω. No
matching components are required. Return loss at the RF
port is typically better than 17dB over a 1400MHz to
3000MHz frequency range, and return loss at the LO
ports is typically better than 16dB over a 1900MHz to
3000MHz frequency range. RF and LO inputs require
only DC-blocking capacitors for interfacing.
The IF output impedance is 50Ω (differential). For evaluation, an external low-loss 1:1 (impedance ratio) balun
transforms this impedance to a 50Ω single-ended output (see the Typical Application Circuit).
Bias Resistor
Bias current for the LO buffer is optimized by fine tuning resistor R1. If reduced current is required at the
expense of performance, contact the factory for details.
If the ±1% bias resistor values are not readily available,
substitute standard ±5% values.

Exposed Pad RF/Thermal Considerations
The EP of the MAX2041’s 20-pin thin QFN-EP package
provides a low thermal-resistance path to the die. It is
important that the PC board on which the MAX2041 is
mounted be designed to conduct heat from the EP. In
addition, provide the EP with a low-inductance path to
electrical ground. The EP MUST be soldered to a
ground plane on the PC board, either directly or
through an array of plated via holes.

be applied to VCC before digital logic is applied to
LOSEL (see the Absolute Maximum Ratings). LO1 and
LO2 inputs are internally matched to 50Ω, requiring
only a 22pF DC-blocking capacitor.
A two-stage internal LO buffer allows a wide-input power
range for the LO drive. The on-chip low-loss balun,
along with an LO buffer, drives the double-balanced
mixer. All interfacing and matching components from
the LO inputs to the IF outputs are integrated on chip.
