GaAs DOUBLE-BALANCED MIXER
MM1-0626SSM
The MM1-0626SSM is a highly linear passive GaAs double
balanced MMIC mixer suitable for both up and downconversion applications. As with all Marki Microwave mixers, it
features excellent conversion loss, isolation and spurious
performance across a broad bandwidth and in a small form
factor. The MM1-0626SSM is available in a lead-free, RoHS
compliant QFN surface mount package and is compatible with
standard leaded and lead-free PCB reflow soldering
processes. The MM1-0626SSM is a superior alternative to
Marki Microwave surface mount M1 and M3 mixers.

1. Configuration A/B refer to the same part number (MM1-0626SSM) used in one of two different ways for optimal spurious
performance. For the lowest conversion loss, use the mixer in Configuration A (port 1 as the LO input, port 2 as the RF input or
output). If you need to use a lower LO drive, use the mixer in Configuration B (port 1 as the RF input or output, port 2 as the LO
input). For optimal spurious suppression, experimentation or simulation is required to choose between Configuration A and B. For
more information, see here.

Downconversion Spurious Suppression
Spurious data is taken by selecting RF and LO frequencies (+mLO+nRF) within the 6 to 26.5 GHz RF/LO bands, which
create a 100 MHz IF spurious output. The mixer is swept across the full spurious band and the mean is calculated. The
numbers shown in the table below are for a -10 dBm RF input. Spurious suppression is scaled for different RF power
levels by (n-1), where “n” is the RF spur order. For example, the 2RFx2LO spur is 74 dBc for the A configuration for a
-10 dBm input, so a -20 dBm RF input creates a spur that is (2-1) x (-10 dB) dB lower, or 84 dBc.

Upconversion Spurious Suppression
Spurious data is taken by mixing a 100 MHz IF with LO frequencies (+mLO+nIF), which creates an RF within the 6 to
26.5 GHz RF band. The mixer is swept across the full spurious output band and the mean is calculated. The numbers
shown in the table below are for a -10 dBm IF input. Spurious suppression is scaled for different IF input power levels by
(n-1), where “n” is the IF spur order. For example, the 2IFx1LO spur is typically 73 dBc for the A configuration for a -10
dBm input, so a -20 dBm IF input creates a spur that is (2-1) x (-10 dB) dB lower, or 83 dBc.

Operation
IF Port – Used as input on an upconversion, output on downconversion, or LO port in a band shifting application. Signals should be connected
by 50 ohm microstrip or coplanar traces to well matched broadband 50 ohm sources and loads. Blocking capacitor is recommended if DC
voltage is present on the line.
RF Port – Used as input on a downconversion, output on upconversion, or output in a band shifting application. Signals should be connected
by 50 ohm microstrip or coplanar traces to well matched broadband 50 ohm sources and loads.
Filtering and Matching- Filtering is generally desired for spurious and image removal on the output port of the mixer. Reflective filters can
cause out of band signals to reflect back into the mixer and cause conversion loss ripple, erroneous spurs, and other undesired behaviors. To
eliminate these problems it is recommend that the filters be placed as close to the output port as possible. If undesired behavior is still
observed, a diplexer with one port terminated or a 1-3 dB attenuator may reduce this problem.
RF Ground – The ground paddle of the QFN should be connected to a low noise RF ground with very low electrical resistance for high
frequency operation.
LO Port – The noise floor of the LO input signal should be less than the value of the noise floor plus isolation of the mixer, or a filter is
recommended to prevent reduction in dynamic range. An LO amplifier is required if the LO power is below the recommended drive level. It is
important to use an amplifier with a broadband 50 ohm match such that it does not reflect spurious signals back into the mixer or other system
circuitry.

DATA SHEET NOTES:
1. Mixer Conversion Loss Plot IF frequency is 100 MHz.
2. Mixer Noise Figure typically measures within 0.5 dB of conversion loss for IF frequencies greater than 5 MHz.
3. Conversion Loss typically degrades less than 0.5 dB at +100°C and improves less than 0.5 dB at -55°C.
4. Unless otherwise specified, data is taken with +20 dBm LO drive.
5. Specifications are subject to change without notice. Contact Marki Microwave for the most recent specifications and data sheets.
6. Catalog mixer circuits are continually improved. Configuration control requires custom mixer model numbers and specifications.
