WJZ2020 Broadband Surface Mount Mixer Product Features x x x x x x x +29 dBm Input IP3 RF: 800 – 1000 MHz LO: 700 – 900 MHz IF: 20 – 100 MHz +17 dBm LO Drive Level No Internal Solder Connections Lead Free/RoHS-compliant SMT package x No External Bias Required Product Description The WJZ2020 is a passive double-balanced diode-ring mixer that provides high dynamic range performance in a Lead Free/ RoHS-compliant surface mount package. The mixer is nominally driven with a LO input power of +17 dBm 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 communications and Navigation markets.
