WJZ2020 Broadband Surface Mount Mixer Product Features x +29 dBm Input IP3 x RF: 800 – 1000 MHz x LO: 700 – 900 MHz x IF: 20 – 100 MHz x +17 dBm LO Drive Level x No Internal Solder Connections x Lead Free/RoHS-compliant SMT package x No External Bias Required Product Description Functional Diagram 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. 1 2 3 LO 8 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. 4 RF 7 6 5 IF Top View Applications x Up/down frequency conversion x Phase Detector x Image Rejection x Current Controlled Attenuator Specifications Parameter Units SSB Conversion Loss Port-to-Port Isolation L-R L-I R-I 3rd Order Input Intercept Point 1dB Input Compression Point VSWR RF Port LO Port IF Port LO Drive Level Min dB dB dB dB dBm dBm dBm 27 20 Typ Max 6.2 7.7 Notes See note 1.
