Product Description
The TQ3632 is a low current, 3V, RF LNA IC designed specifically for PCS band
CDMA applications. It’s RF performance meets the requirements of products
designed to the IS-95 specifications. The TQ3632 is designed to be used with the
TQ5631 or TQ5633 (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 or TQ5633 (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 Ω, greatly simplifying the design and minimizing the
number of external components. The TQ3632 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.
