The mixer is nominally driven with a LO input power of +17 d Bm to optimize its performance. Other WJZ models are available for other LO drive levels. Targeted applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in 2.5G and 3G GSM/CDMA/W-CDMA systems. The device can also be used in Radar, Satellite, Test / Medical Instruments, Avionics munications and Navigation markets.
