MH205A

High Linearity Cellular-Band MMIC Mixer

Product Information

Product Features

Product Description

Functional Diagram

The MH205A is a passive GaAs MESFET mixer that

provides high dynamic range performance in a low-cost

• +35 dBm Input IP3

• 7 dB Conversion Loss

• RF: 800 – 960 MHz

• LO: 700 – 890 MHz

lead-free/green/RoHS-compliant SOIC-8 package.

WJ’s

MH205A uses patented techniques to realize +35 dBm

Input IP3 at an LO drive level of +17 dBm and can be used

for upconverting or downconverting low-side LO

applications. This single monolithic integrated circuit does

not require any external baluns or bias elements.

• IF:

70 – 120 MHz

• +17 dBm Drive Level

• Lead-free / RoHS-compliant /

Typical applications include frequency up/down

conversion, modulation and demodulation for receivers and

transmitters used in 2.5G and 3G GSM/CDMA/wCDMA

mobile infrastructure in the cellular frequency band.

1. Test conditions unless otherwise noted: RF / IF = 803 / 70 and 963 / 70 with a low-side LO at +17 dBm in a downconverting application at 25 °C.

The diplexer shown on the application circuit is used in the test fixture.

2. Assumes LO injection noise is filtered at the thermal noise floor, -174 dBm/Hz, at the RF, IF, and Image frequencies.

3. IIP3 is measured with Δf = 1 MHz with RFin = 0 dBm / tone.

4. The return loss is measured after the diplexer which splits the RF and IF signals from the mixer.
