HFA3765 Product details

Description
The HFA3765 is a monolithic quadrature 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
