required. Typical applications include frequency up/
down conversion, modulation, and demodulation in
receivers and transmitters for base station and
portable systems.
The MAMXSS0012 employs GaAs FETs as mixing
elements to achieve a very wide dynamic range in a
low cost plastic package. The mixer operates with
LO drive levels of +3 dBm to +8 dBm. The LO port
may be externally tuned for operation in various
frequency bands.
M/A-COM's GaAs IC is fabricated using a mature
0.5 micron gate length GaAs MESFET process. The
process features full passivation for increased
performance and reliability.

Harmonic of RF
The spurious table shows the spurious signals resulting from the
mixing of the RF and LO input signals, assuming down
conversion. Mixing products are indicated relative to the IF. The
lower frequency mixing term is shown for two different RF input
levels. The top number is for an RF input power of 0 dBm, the
lower number is for -10 dBm.
