Product Description
The TQ5631 is a 3V, RFAmplifier/Mixer IC designed specifically for PCS band CDMA
applications. It’s RF performance meets the requirements of products designed to
the IS-95 standards. The TQ5631 is designed to be used with the TQ3631 (CDMA
LNA) which provides a complete CDMA receiver for 1900MHz phones.
The RFA/Mixer incorporates on-chip switches which determine gain select states.
When used with the TQ3631 (CDMA 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 minimum. The TQ5631 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 PCS band mobile phones.
