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 powerdown 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. 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.
