PRELIMINARY

130MHz CDMA/AMPS Quadrature

Modulator and AGC

Features

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

The HFA3767 is a monolithic bipolar

quadrature modulator with gain control

for CDMA/AMPS cellular applications.

An upconverter quadrature mixer and

an output gain control stage with better

• 130MHz AGC Amplifier/Attenuator range . . . . . . . .>70dB

• Low LO Drive Level . . . . . . . . . . . . . . . . . . . . . . . .-10dBm

• Power Enable/Disable Control

• Single Supply Battery Operation . . . . . . . . . . . 2.7 to 3.3V

than 70dB of dynamic range are integrated in the design. 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

HFA3767 is one of the four chips in the PRISM™ chip set

and is housed in a 20 lead SSOP package ideally suited to

cellular handset applications.

Applications

• IS95A CDMA/AMPS Dual Mode Handsets

• Wideband CDMA Handsets

• Full Duplex Transceivers

• CDMA/TDMA Packet Protocol Radios

• Portable Battery Powered Equipment
