Product Description

Low-current operation

Small QSOP-16 plastic package

Few external components

The TQ5122 is a 3V, RF receiver IC designed specifically for Cellular band TDMA

applications. It’s RF performance meets the requirements for products designed to the

IS-136 TDMA and the AMPS standards. The TQ5122 includes a power–down mode

which allows current saving during standby and the non-operating portion of the TDMA

pulse. The TQ5122 contains LNA and Mixer circuits matched to the 800MHz cellular

band.

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 TQ5122

achieves excellent RF performance with low current consumption which yields long

standby times in portable applications. The small QSOP-16 package is ideally suited

for Cellular band mobile phones.
