The HFA3667 UpConverter is a

monolithic bipolar upconverter

with gain control for CDMA/AMPS

cellular applications. Manufac-

tured in the Intersil UHF1X process, the device consists of

a double balanced mixer followed by a variable gain power

preamplifier. The device is designed for high output

compression of +13dBm and requires low drive levels from

the local oscillator. The HFA3667 is one of the four chips in

the PRISM™ chip set and is housed in a small outline

28 lead SSOP package ideally suited for cellular handset

applications.
