MH303 The Communications Edge TM Cellular-band Quad-FET Mixer Product Features * * * * * * * Product Description +28 dBm IIP3 RF 820 - 920 MHz IF 20 - 100 MHz Low-side LO configuration +13 dBm LO Drive Level High L-I & L-R Isolation (>38 dB) Lead-free/green/RoHS-compliant 6-pin 3x3 mm DFN package * No External Bias Required Applications * 2.5/3G GSM/CDMA/W-CDMA Product Information Functional Diagram 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) leadfree/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.

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. The conversion loss includes the loss of an IF transformer (M/A COM ETC1-1-13, nominal loss 0.7 dB at 70 MHz). Input IP3 is measured with two tones with an input power of +3 dBm / tone separated by 1 MHz. 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.
