No External Bias Required
The MH303 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 MH303 uses patented techniques to realize +28
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 cellular-band 3G mobile
infrastructure.

1. Data was taken using an application board in a 50 system, with a low side LO at +13 dBm in a downconverting application at 25°C with an IF frequency = 70 MHz.
2. An IF frequency of 70 MHz is a nominal frequency. The IF frequency can be specified by the user within the constraints of the specified minimum and maximum RF and LO frequency range.
3. The conversion loss includes the loss of an IF transformer (M/A COM ETC1-1-13, nominal loss 0.7 dB at 70 MHz).
4. Input IP3 is measured with 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.
