Product Description
The TQ5633 is a 3V, RF Amplifier/Mxer IC designed specifically for PCS band
CDMA applications. It’s RF performance meets the requirements of products
designed to the IS-95 standard. The TQ5633 is designed to be used with an IF
frequency of 110MHz, and uses a balanced mxer to achieve IF rejection. When
used with the TQ3631 or TQ3632 (CDMA LNAs) it provides a complete CDMA
receiver for 1900MHz phones.
The RF Amplifier/Mxer incorporates on-chip switches which determne two gain
select states. The RF and LO input ports are internally matched to 50
, greatly
simplifying the design and keeping the number of external components to a
mnimum The TQ5633 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.
