Product Description
The TQ5633 is a 3V, RF Amplifier/Mixer 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 mixer to achieve ½ IF rejection. When
used with the TQ3631 or TQ3632 (CDMA LNAs) it provides a complete CDMA
receiver for 1900MHz phones.
The RF Amplifier/Mixer incorporates on-chip switches which determine two gain
select states. The RF and LO input ports are internally matched to 50 Ω, greatly
simplifying the design and keeping the number of external components to a
minimum. 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.
