Product Description
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 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 part is ideally suited for Cellular band mobile
phones.
