Product Description
Functional Diagram
The MH302 is a passive Quad-MOSFET mixer that
provides high dynamic range performance in a low cost
3x3 mm 6-pin DFN (Dual Flat No-Lead) lead-
free/green/RoHS-compliant package.
WJ’s MH302 uses patented techniques to realize +27
dBm Input IP3 at an LO drive level of +13 dBm when
used in a simple application circuit with a low-side LO
configuration. The LO can also be driven with higher
power levels up +20 dBm to achieve higher IP3
performance. This mixer integrates internal circuitry to
provide single-ended interfaces for the RF & LO ports.
Typical applications include frequency up/down
conversion, modulation and demodulation for receivers
and transmitters used in 3G UMTS, PCS, and
DCS1800 mobile infrastructure.

1. Data was taken using an application board in a 50 Ω system, with a low side LO at +13 dBm in a downconverting application at 25 °C with an IF frequency = 260 MHz.
2. An IF frequency of 260 MHz is a nominal frequency. The IF frequency can be specified by the user within the constraints of the specified minimum and maximum RF & LO frequency range.
3. The conversion loss includes the loss of an IF transformer (M/A COM ETK4-2T, nominal loss 0.7 dB at 260 MHz).
4. Input IP3 is measured using two tones with an input power of +3 dBm / tone separated by 1 MHz.
5. Although the input P1dB level is much higher, the continuous RF input power should not exceed +12 dBm. Operation above +12 dBm may cause permanent damage.
