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.
