Description
The HFA3665 is a monolithic bipo-
lar downconverter for CDMA/AMPS
cellular applications. Manufactured
in the Intersil UHF1X process, the
device consists of a low noise cascode amplifier, a double
balanced downconversion mixer and a pair of linearized and
temperature
compensated
sources for external RF AGC applications. In addition, the
device offers two independent and selectable differential
mixer IF output ports to be used with dual mode IF filters and
requires low drive levels from the local oscillator. The
HFA3665 is one of the four chips in the PRISM chip set
and is housed in a small outline 28 lead SSOP package ide-
ally suited for cellular handset applications.
