Product Description
The TQ3631 is a 3V, RF LNA IC designed specifically for PCS band CDMA
applications. It鈥檚 RF performance meets the requirements of products designed to
the IS-95 specifications. The TQ3631 is designed to be used with the TQ5631
(CDMA mixer) which provides a complete CDMA receiver for 1900MHz phones.
The LNA incorporates on-chip switches which determine high, low and bypass mode
select. When used with the TQ5631 (CDMA RFA/mixer), four gain steps are
available for use which provide low current/high IP3 and gain. The RF output port is
internally matched to 50
鈩?/div>
, greatly simplifying the design and minimizing the number
of external components. The TQ3631 achieves excellent RF performance with low
current consumption, supporting long standby and talk times in portable applications.
Coupled with the very small SOT23-8 package, the part is ideally suited for PCS
band mobile phones.
