RF2459
3V PCS DOWNCONVERTER
Typical Applications
• CDMA/TDMA/DCS1900 PCS Systems
• PHS 1500/WLAN 2400 Systems
• General Purpose Downconverter
• Micro-Cell PCS Base Stations
• Portable Battery-Powered Equipment
Product Description
The RF2459 is a monolithic integrated downconverter for
PCS, PHS, and WLAN applications. The IC contains all of
the required components to implement the RF functions
of the downconverter. It contains a double-balanced Gil-
bert cell mixer and a balanced IF output. The mixer’s high
third-order intercept point makes it ideal for digital cellular
applications. The IC is designed to operate from a single
3V power supply.
