130MHz CDMA/AMPS Quadrature
Modulator and AGC
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
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.
