Cellular-Band Quad-FET Mixer

Product Features

Applications

Specifications

1. Data was taken using an application board in a 50

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.

Absolute Maximum Ratings

Operation of this device above any of these parameters may cause permanent damage.

Product Description

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 various current and next

generation RFID technologies such as EPC, ISO, ETSI,

and ANSI. Their small size makes them ideal for

PCMCIA applications.
