Features
 Power-Down, “Sleep” Mode
 Single 2.8V operation
Product Description
 Low-current operation
 Small QSOP-16 plastic package
The TQ5622 is a 3V, RF receiver IC designed specifically for PCS band TDMA
applications. It’s RF performance meets the requirements for products designed to the
IS-136 TDMA standards. The TQ5622 includes a power–down mode which allows
current saving during standby and the non-operating portion of the TDMA pulse. The
TQ5622 contains LNA and Mixer circuits matched to the 1900MHz PCS band.

Few external components
The mixer uses a high-side LO frequency. The IF has a usable frequency range of 85
to 150MHz. The LNA Output and Mixer Input ports are internally matched to simplify
the design and keep the number of external components to a minimum. The TQ5622
achieves excellent RF performance with low current consumption which gives long
standby times in portable applications. The small QSOP-16 package is ideally suited
for PCS band mobile phones.
