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 , 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.
