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 PIN diode biasing current

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.
