GaAs DOUBLE-BALANCED MIXER
MM1-2567LS
The MM1-2567LS is a passive GaAs double balanced MMIC
mixer suitable for both up and down-conversion 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 MM1-2567LS
is available in a connectorized package. Owing to its passive
balun circuitry, the mixer can be used in two different
configurations: Configuration A for highest efficiency and
Configuration B for the best spurious performance and lowest
LO drive. Refer to page 2 for more information on the operating
configurations.

1. Configuration A/B refer to the same part number (MM1-0320H) 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 25 to 67 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 53 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 53 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 25 to 67
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 46 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 56 dBc.

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 for LO drives 2 dB below the lowest and 3 dB above highest nominal LO drive levels.
4. Conversion Loss typically degrades less than 0.5 dB at +100°C and improves less than 0.5 dB at -55°C.
5. Unless otherwise specified, Configuration A data is taken with +13 dBm LO drive, and Configuration B is taken with +9 dBm drive
6. Specifications are subject to change without notice. Contact Marki Microwave for the most recent specifications and data sheets.
7. Catalog mixer circuits are continually improved. Configuration control requires custom mixer model numbers and specifications.
