The TQ5121 is a 3V, RF receiver IC designed specifically for Cellular band TDMA applications. It's RF performance meets the requirements of products designed to the IS-136 and AMPS standards. The TQ5121 is pin compatible with TQ9222, which enables handset designers to use strategic board platform strategy. The TQ5121 contains LNA+Mixer circuits to handle the 800MHz cellular band.
The mixer uses a high-side LO frequency, with the IF covering a range of 70 to 140MHz. Most RF ports are internally matched to 50 W, greatly simplifying the design and keeping the number of external components to a minimum. The TQ5121 achieves good RF performance with low current consumption, supporting long standby times in portable applications. Coupled with the very small QSOP-16 package, the part is ideally suited for Cellular band mobile phones.

TQ5122 General 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 powerdown 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.
