DESCRIPTION
The SA3603 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 Cellular-band communication systems.
The LNA has a 1.6 dB noise figure at 881 MHz with 17.5 dB gain
and an IIP3 intercept of –4 dBm. The single-ended input, single
balanced mixer has a 9.5 dB noise figure with 7.5 dB gain and IIP3
of +6.0 dBm at 881 MHz.
