DESCRIPTION
The SA3604 is an integrated Low-Noise Amplifier (LNA) and mixer
designed in a 30 GHz f
T
advanced BICMOS process, Qubic3, for
high-performance, low power PCS-band communication systems.
The LNA has a 1.9 dB noise figure at 1960 MHz with 17.5 dB gain
and an IIP3 intercept of –4 dBm. The single-ended input, double
balanced mixer has a 9.5 dB noise figure with 8 dB gain and IIP3 of
+6.0 dBm at 1960 MHz.
