Product Description
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 mxer) which provides a complete CDMA receiver for
800MHz dual-mode phones.
The LNA incorporates on-chip switches which determne CDMA, AMPS, and bypass
mode select. When used with the TQ5131 (CDMA RFA/mxer), four gain states are
available. The RF output port is internally matched to 50
, greatly simplifying the
design and keeping the number of external components to a mnimum 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.
