Description
The MAMX-011009 is a lead-free 1.5 x 1.2 mm
TDFN surface mount plastic packaged sub-harmonic
mixer. No bias is required, although DC-offset on the
IF port can improve performance.
The MAMX-011009 can be used for up or down
frequency conversion. The mixer integrates an 180o
balanced diode topology that allows the LO to be
injected at ½ the mixing LO frequency. This
improves LO isolation and simplifies system
requirements.
When used as a down converting mixer, it can
convert RF port signals from 14 to 32 GHz to IF port
signals of DC to 7 GHz.
When used as an up converting mixer, it can convert
IF port signals from DC to 7 GHz to RF port signals
of 14 to 32 GHz.
In either mode the +15 dBm LO signal of 4 to 20
GHz drives the frequency conversion at ½ the
mixing product. Typical conversion loss is 11 dB
with 2xLO and 3xLO isolation typically greater than
50 dB. Typical input IP3 is greater than +12 dBm. Ordering Information3,4

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
Class 1A (HBM) devices.

PCB Layout
PCB Footprint Application Information
The MAMX-011009 is designed to be economical
and easy to use. By employing a sub-harmonic
topology, the user only has to deal with one high
frequency port (RF). This simplifies system design,
lowers cost, and combined with an ultra-small
plastic package delivers a superior system solution.
The MAMX-011009 design allows bi-direction
frequency conversion (IF to RF or RF to IF). The
conversion loss, isolation, and linearity are similar
either way.
For proper up or down frequency mixing the
MAMX-011009 must be driven with sufficient power
to activate the mixing diodes, typically 14 dBm or
higher. We highly recommend M/A-COM
Technology Solutions MAAM-011101, which has
been engineered to match the LO requirements of
the MAMX-011009.
Grounding
The printed circuit board (PCB) layout is simple for
the MAMX-011009 since no external components
are needed. The LO port is internally DC blocked;
DC voltages up to 20 V are acceptable. However,
proper grounding must be used for operation. It is
recommended that the total common ground
inductance not exceed 0.03 nH. This is equivalent
to placing a least four 8-mil (200 μm) diameter vias
under the device, assuming an 8-mil (200 μm) thick
RF layer to ground. More ground vias are recom-
mended if possible.

Applications Section
System usage of this Mixer
The MAMX-011009 is designed to be a building
block for more complex systems. The LO buffer
amplifier is deliberately left separate so as to
increase flexibility. If the LO buffer is desired, we
recommend the MAAM-011101 4-20 GHz amplifier
from M/A-COM Technology Solutions.
Typical usage of this mixer includes:
Feedback systems:
The low cost and simple use of the MAMX-011009
allows a low cost down-conversion feedback
system for pre-distortion or phase lock systems.
Combined with the M/A-COM Technology
Solutions MAAM-011101 for LO drive and printed
PCB couplers and the system is complete.
Single Balanced Application:
The MAMX-011009 has only one high frequency
port, so signal routing is simplified.
Double Balanced Image Rejection:
Combine two ultra-small MAMX-011009 mixers
with 90o (Lange) or 180o splitters for image
rejection.
I/Q Modulation:
I/Q quadrature drive two MAMX-011009 mixers into
a summer or 90o (Lange) for a direct conversion
system.
