Description
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.
