High IP3 performance
Few external components
The TQ3M31 is a 2.8V, RF dual band LNA IC designed specifically for Cellular &PCS
band CDMA/AMPS applications. It鈥檚 RF performance meets the requirements of
products designed to the IS-95 and AMPS standards. The TQ3M31 is designed to
be used with the TQ5131 (Cellular CDMA/AMPS mixer) and the TQ5631 (PCS
CDMA mixer) which provides a complete Tri-Mode CDMA receiver for 800MHz dual-
mode and 1900MHz phones.
The LNA incorporates on-chip switches which determine CDMA, AMPS, and bypass
mode select. When used with the TQ5131 and TQ5631, four gain states are
available in each band. The RF output port is internally matched to 50
鈩?/div>
, greatly
simplifying the design and keeping the number of external components to a
minimum. The TQ3M31 achieves good RF performance with low current
consumption, supporting long standby times in portable applications. Coupled with
the very small MLF 3x3 package, the part is ideally suited for Cellular & PCS band
mobile phones.
