Product Description

ꢀ Mode Select

The TQ3131 is a 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 TQ3131 is designed to be used with the

TQ5131 (CDMA/AMPS mixer) which provides a complete CDMA receiver for

800MHz dual-mode phones.

ꢀ High IP3 performance

ꢀ Few external components

The LNA incorporates on-chip switches which determine CDMA, AMPS, and bypass

mode select. When used with the TQ5131 (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 TQ3131

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.
