Description
M/A-COM’s SA65-0003 is an integrated assembly
containing a GaAs FET MMIC LNA and GaAs FET
mixer. This device is packaged in a 16-leaded
QSOP plastic surface mount package. The amplifier
can be biased with either +3V or +5V, the mixer
requires no DC bias. The conversion gain of the
integrated combination is typically 6 dB at +3V bias
and 8 dB at +5V bias. The SA65-0003 is ideally
suited for RF/IF communications applications
requiring down conversion with some gain. This
MCM contains a mixer that is fabricated using a
mature 1-micron GaAs process, it also contains an
LNA that is fabricated using a low cost mature
0.5-micron gate length GaAs MESFET process.
Both die feature full passivation for increased
performance and reliability.

The spurious table shows the spurious signals resulting from the
mixing of the RFIN and LO input signals, assuming down
conversion. The number of dB below the conversion loss level
indicates the mixing products. The lower frequency mixing term
is shown for two different input levels. The top number is for an
RFIN power level of –19 dB; the lower number is for –29 dB.
Assuming the LNA gain is approximately 14 dB, the mixer input
will see approximately –5 dB and –15 dB.
