Functional Diagram
General Description
TE
High Carrier Suppression: 38 dBc
The HMC495LP3 & HMC495LP3E are low noise
Wideband Direct Quadrature Modulator RFICs which
are ideal for digital modulation applications from 250 3800 MHz including; Cellular/3G, Broadband Wireless
Access & ISM circuits. Housed in a compact 3x3 mm
(LP3) SMT QFN package, the RFIC requires minimal
external components & provides a low cost alternative
to more complicated double upconversion architectures. The RF output port is single-ended and matched
to 50 Ohms with no external components. The LO requires -6 to +6 dBm and can be driven in either differential or single-ended mode while the Baseband inputs will support modulation inputs from DC - 250 MHz
typical. This device is optimized for a supply voltage of
+3.3V @ 108 mA and will provide stable performance
over a +3V to +3.6V range.

Calibrated vs. Uncalibrated Test Results
During the Uncalibrated Sideband and Carrier Suppression tests, care is taken to ensure that the I/Q signal paths from
the Vector Signal Generator (VSG) to the Device Under Test (DUT) are equal. The “Uncalibrated, +25 °C” Sideband
and Carrier Suppression plots were measured at room temperature, while the “Uncalibrated, over Temperature”
Sideband and Carrier Suppression plots represent the worst case uncalibrated suppression levels measured at T=
-40 °C, +25 °C, and +85 °C.
The “Calibrated, + 25 °C” Sideband Suppression data was plotted after a manual adjustment of the I/Q amplitude
balance and I/Q phase offset (skew) at +25 °C, and at each LO input power level. The +25 °C adjustment settings
were held constant during tests over temperature. The “Calibrated, over Temperature” plots represent the worst case
calibrated Sideband Suppression levels at T= -40 °C, +25 °C, and +85 °C.
The “Calibrated, +25 °C” Carrier Suppression data was plotted after a manual adjustment of the Ip/In & Qp/Qn DC
offsets at +25 °C, and at each LO input power level. The +25 °C adjustment settings were held constant during tests
over temperature. The “Calibrated, over Temperature” plots represent the worst case Carrier Suppression levels
measured at T= -40 °C, +25 °C, and +85 °C.

GND
These pins and the ground paddle must be connected to a
high quality RF/DC ground.
LOP, LON
Differential LO input ports. This device may be driven in
either differential or single ended mode. In single ended
mode, one port should be driven by the LO source while
the other port may be terminated with a 50Ω resistor to
ground. An external shunt 68Ω resistor is used to improve
VSWR, while an external 100 pF capacitor is required
to prevent DC supply voltage from appearing on the
customer’s PC board.
VB2
Bias Voltage for the LO stage. This voltage will affect the
Sideband Suppression, the Output Noise Floor and the
Power Consumption. The ideal voltage range for this port
is between +2.7 Vdc and +3.0 Vdc. The nominal current for
this port is 5.3 mA.
5
Qn, Qp
B
6, 7
Differential Quadrature baseband input. These are
high impedance ports. The nominal recommended bias
voltage is between 1.0 - 1.15V. The nominal recommended
baseband input voltage is 800 mV peak to peak differential.
By adjusting the DC bias voltage on ports Qn & Qp, the
Carrier Suppression of the device can be optimized for a
specific frequency band and LO power level. The typical
offset voltage for optimization is less than 5 mV.
The amplitude and phase difference between the I and Q
inputs can be adjusted in order to optimize the Sideband
Suppression for a specific frequency band
and LO power level.

RFP
RF Output port. This port is matched to 50Ω. A series
capacitor should be connected to this port in order to
prevent the DC supply voltage from appearing on the
customer’s PC board.

The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be connected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.

Baseband input frequency range is dependent on value of C4, C5, C9 and C10. The value of 10 pF was chosen to give a typical
response of DC - 250 MHz. Input frequency range can be extended up to 1 GHz with possible degradation of LO leakage and
broadband noise floor response by decreasing the value of C4, C5, C9 & C10.
