Product Description

The TQ9222 is a 3-V, RF receiver IC designed specifically for dual-band TDMA
applications. Its RF performance meets the requirements of products designed to
the IS-136 and GSM standards. The TQ9222 is pin compatible with TQ5121 (cellular
band LNA/Mixer) which enables handset designers to use strategic board platform
strategy.

The TQ9222 contains two separate LNA+Mixer circuits to handle both the 800 MHz
cellular band and the 1900 MHz PCS band. The mixers use a high-side LO
frequency, with the IF covering a range of 70-140 MHz. IF frequencies below 120
MHz are possible due to the ½-IF spurious signal rejection in the 1900 MHz
LNA+Mixer. The IF outputs are designed for use of a common IF frequency. Most
RF ports are internally matched to 50Ω, greatly simplifying the design and keeping
the number of external components to a minimum. Separate supply voltage
connections provide the required flexibility for dual-band operation. The TQ9222
achieves good RF performance with low current consumption, supporting long
standby times in portable applications. Coupled with the very small QSOP-24
package, the part is ideally suited for dual-band mobile phones.
