Product Description

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.
