AGC and Quadrature IF Demodulator

Features

Description

The HFA3765 is a monolithic quadra-

ture demodulator and a gain control

amplifier stage with 90dB of dynamic

DescriptionIF Operation10MHz to 250MHz

• I/Q Amplitude and Phase Balance . . 0.5dB, 2 Degrees

• Voltage Gain. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .>60dB

• AGC Range. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .90dB

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.
