Description
The HFA3765 is a monolithic quadra-
ture demodulator and a gain control
amplifier stage with 90dB of dynamic
range for CDMA/AMPS cellular applications. Two amplifier
inputs are provided for interfacing different IF input filters. A
local oscillator input requires low drive levels and a divide by
two phase shifter with duty cycle compensation achieves
excellent phase and amplitude balance properties. The
HFA3765 is one of the four chips in the PRISM chip set
and is housed in a 28 lead SSOP package ideally suited to
cellular handset applications.
