Product Description

The TQ5132 is a 3V, RFA/Mixer IC designed specifically for Cellular band
CDMA/AMPS applications. It’s RF performance meets the requirements of products
designed to the IS-95 and AMPS standards. The TQ5132 is designed to be used
with the TQ3131 or TQ3132 (CDMA/AMPS LNA) which provides a complete CDMA
receiver for 800MHz dual-mode phones.

The RFA/Mixer incorporates on-chip switches which determine CDMA, AMPS and
bypass mode select. When used with the TQ3131 or TQ3132 (CDMA/AMPS LNA),
four gain steps are available. The RF input port is internally matched to 50 Ω,
greatly simplifying the design and keeping the number of external components to a
minimum. The TQ5132 achieves good RF performance with low current
consumption, supporting long standby times in portable applications. Coupled with
the very small SOT23-8 package, the part is ideally suited for Cellular band mobile
phones.
