Product Description


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.

Power-Down, “Sleep” Mode
Single 2.8V operation
Low-current operation
Small QSOP-16 plastic package
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 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.
