General Description

SAC3604 is a GaAs MMIC T/R frequency conversion die that switches between up and down conversion, with 0.7 to 2 GHz RF and LO and DC to 1 GHz IF. Conversion gain is 6 dB up and 5.5 dB down at 0 dBm LO.

It integrates a bidirectional RF amp, LO driver, balanced mixer and T/R switching. Output P1dB is 12 dBm up and 4 dBm down, from +5 V with 80 + 50 mA listed. The 3.45 x 3.1 x 0.1 mm die takes conductive epoxy attach and suits half duplex L-band radios.
