The TQ3132 is a low current, 3V, RF LNA 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 TQ3132 is designed to be used with the TQ5131 or TQ5132 (CDMA/AMPS mixer) which provides a complete CDMA receiver for 800MHz dual-mode phones.
The LNA TQ3132 incorporates on-chip switches which determine CDMA, AMPS, and bypass mode select. When used with the TQ5131 or TQ5132 (CDMA RFA/mixer), four gain states are available. The RF output port is internally matched to 50 Ω, greatly simplifying the design and keeping the number of external components to a minimum. The TQ3132 achieves good RF performance with low current consumption, supporting long standby times in portable applications. Coupled with the very small SOT23-8 package, the TQ3132 is ideally suited for Cellular band mobile phones.
