Product Description
Functional Diagram
The WJZ1000 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 +10
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.
