Description

The TQ5131 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 TQ5131 is designed to be used with the TQ3131 (CDMA/AMPS LNA) which provides a complete CDMA receiver for 800MHz dual-mode phones.

The RFA/Mixer TQ5131 incorporates on-chip switches which determine CDMA, AMPS and bypass mode select. When used with the TQ3131 (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 TQ5131 achieves good RF performance with low current consumption, supporting long standby times in portable applications. Coupled with the very small SOT23-8 package, the TQ5131 is ideally suited for Cellular band mobile phones.
