GENERAL DESCRIPTION
The HMC520A is a compact gallium arsenide (GaAs),
monolithic microwave integrated circuit (MMIC), in-phase
quadrature (I/Q) mixer in a 24-terminal, RoHS compliant,
ceramic leadless chip carrier (LCC) package. The device can
be used as either an image reject mixer or a single sideband
upconverter. The mixer uses two standard double balanced
Rev. A
mixer cells and a 90° hybrid fabricated in a GaAs, metal
semiconductor field effect transistor (MESFET) process. The
HMC520A is a smaller alternative to a hybrid style image reject
mixer and a single sideband upconverter assembly. The
HMC520A eliminates the need for wire bonding, allowing the
use of surface-mount manufacturing techniques.

Thermal performance is directly linked to printed circuit board
(PCB) design and operating environment. Careful attention to
PCB thermal design is required.
θJA is the natural convection, junction to ambient thermal
resistance measured in a one cubic foot sealed enclosure. θJC is
the junction to case thermal resistance.

PDISS is a theoretical number calculated by (TJ − 85°C)/θJC.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.

HMC520A
THEORY OF OPERATION
The HMC520A is a GaAs, MMIC, I/Q mixer in a 24-terminal,
RoHS compliant, ceramic LCC package and operates over the
−40°C to +85°C temperature range. The EV1HMC520ALC4
evaluation board is also available from Analog Devices, Inc. The
HMC520A is a passive, wideband, I/Q MMIC mixer that can be
used as either an image reject mixer for receiver operations or as a
single sideband upconverter for transmitter operations. The mixer
uses two standard double balanced mixer cells and a 90° hybrid
fabricated in the GaAs, MESFET process.
With an RF and an LO input frequency range of 6 GHz to 10 GHz
and an IF frequency range of dc to 3.5 GHz, the HMC520A is ideal
for applications requiring a wide frequency range, excellent RF
performance, a simple design with fewer components, and a
small PCB footprint. One HMC520A can replace multiple
narrow-band mixers in a design. The HMC520A eliminates the
need for wire bonding, allowing the use of the surface-mount
manufacturing techniques.
The inherent I/Q architecture of the HMC520A offers excellent
image rejection and thereby eliminates the need for expensive
filtering for unwanted sidebands. The double balanced architecture
of the mixer also provides excellent LO to RF isolation and LO to IF
isolation, and this architecture reduces the effect of LO leakage
to ensure signal integrity. Because the HMC520A is a passive
mixer, the HMC520A does not require any dc power sources.
The HMC520A offers a lower noise figure compared to an
active mixer, ensuring superior dynamic range for high
performance and precision applications.
For both upconversion and downconversion, an external 90°
hybrid is required. See the Applications Information section for
details on interfacing with this external 90° hybrid.

PERFORMANCE TO 13 GHz
This section provides test results at a higher frequency to
13 GHz. Board, traces, and connector losses are not de-embedded
for all measurements. This performance is typical, though not
guaranteed. All measurements were made under the following
conditions: LO = 15 dBm, IF = 1.5 GHz, RF = −10 dBm, and
TA = 25°C, with an external 90° IF hybrid at the IF ports, unless
otherwise noted.

To select the upper sideband (low-side LO) when using as a
downconverter, connect the IF1 pin to the 0° port of the hybrid
and connect the IF2 pin to the 90° port of the hybrid. To select
the lower sideband (high-side LO), connect the IF1 pin to the
90° port of the hybrid and connect the IF2 pin to the 0° port of
the hybrid. The output is from the sum port of the hybrid, and
the difference port is 50 Ω terminated.

Figure 83 shows the typical application circuit for the HMC520A.
To select the appropriate sideband, an external 90° hybrid is
needed. For applications not requiring operation to dc, use an
off chip dc blocking capacitor. For applications that require the
LO signal at the output to be suppressed, use a bias tee or RF
feed as shown in Figure 83. Ensure that the source or sink
current used for LO suppression is
