Product Description
The RF9986 is a monolithic integrated receiver front-end
for PCS, PHS, and WLAN applications. The IC contains
all of the required components to implement the RF func-
tions of the receiver front-end except for the passive filter-
ing and LO generation. It contains an LNA (low-noise
amplifiers), a double-balanced Gilbert cell mixer, a bal-
anced IF output, an LO isolation buffer amplifier, and an
LO output buffer amplifier for providing the buffered LO
signal as an output. The IC is designed to operate from a
single 3.6V power supply.
