ꢀ 110MHz IF Frequency

ꢀ 50 Ω RF and LO inputs

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.
