Product Description
The WJZ1020H 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.

Land Pattern / Mounting Configuration
Notes:
1. Package unit weight is 2.0 grams max.
2. Dimensions are expressed in inches. Dimensions in brackets are millimeter equivalents.
3. Tolerance .XXX +/- .015, .XX +/- .02
4. Package circuit board material: .021” FR-4, 2 lay ers, .025” total thickness.
5. Land pattern ground vias are critical for RF grounding considerations. A minimum of 12 ground
vias (min. diameter of 20 mil or 51μm) underneath the device is required.
6. PC board trace width depends on the board m aterial and thickness.
7. Blocking capacitors are required on the ports (pins 2, 4, 6) if any dc signal is present.
Product Marking
The component will be marked with a
“WJZ1020H” designator followed by an
alphanumeric lot code on the top surface of
the package.
Tape and reel specifications for this part will
be located on the website in the “Application
Notes” section.
