Description

The HFA3667 UpConverter is a monolithic bipolar upconverter with gain control for CDMA/AMPS cellular applications. Manufactured 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.
