... MXR 800 800 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 ...

... BIAS Fig 1. LNA Sections Cellular Band Mixer The cellular band mixer of the TQ9222 is implemented by a common source depletion FET. The mixer is designed to operate on supply voltages from 3V to 5V. An on-chip buffer amplifier simplifies direct connection of the LO input to a commercial VCO at drive levels down to -7dBm. The common- For additional information and latest specifications, see our website: www ...

... Designing the input matching network involves a compromise between optimum noise performance and best input return loss. For example, when the TQ9222 LNA is matched for optimum noise figure (1.35dB @ 880 MHz, and 1.45dB @ 1960 MHz), the input return loss is only about 4dB. On the other hand, when the LNA is matched for best return loss, the LNA noise figure is approximately 1 ...

... One signal generator is set to the LO frequency at its normal LO drive level usually (-7 dBm). The second signal generator (spurious signal) is set to the LO +/- the IF frequency. The combined input power at mixer LO port has to be less than -50 dBm. The results shown in Table 2 indicate a good suppression of the interfering signals. TQ9222 Mixer ohm LO Directional ...

... The frequency response of the LO driver amplifier can be measured using a semi-rigid probe (see Fig. 6) and a network analyzer. Connect port 1 to the LO input (Pin 8) of the TQ9222 with the source power set to deliver -7 dBm. Connect the coaxial probe to Port 2 and place the probe tip approximately 0.1 inch away from either Pin 7 or the inductor ...

... It will depend on the injection mode of the LO signal and the IF frequency being used. For example If the high side injection such as the case of the TQ9222 and the IF = 110 MHz then (theoretically) we worry about the first 5 MHz of the band (1930-1935) only if we have ideal filters. ...
