Product Description
The TQ5131 is a 3V, RFA/Mxer 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/Mxer incorporates on-chip switches which determne 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
, greatly
simplifying the design and keeping the number of external components to a
mnimum 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 part is ideally suited for Cellular band mobile
phones.
