WJ Communications introduces two new highly linear mixers, the MH103A and MH203A.
Both mixers are suitable for WCDMA, CDMA2000 and multi-carrier applications.
Among the benefits of the MH103A and MH203A are high IP3, up to +34 dBm and
a low conversion loss. These passive GaAs MESFET mixers provide high dynamic
range performance in an SOIC-8 package.

| WJ's monolithically integrated MH-series mixers combine high IP3
and low loss. |
The MH103A
Product specifications include:
• RF frequency range — 1900 to 2200 MHz
• LO frequency range — 1600 to 2150 MHz
• IF frequency range — 50 to 300 MHz
• SSB conversion loss — 8.2 dB typical, 10.5 dB maximum
• Noise figure — 8.7 dB
• Input IP3 — +28 dBm minimum, +34 typical
• Input P1dB — +16 dBm typical
• LO-RF isolation — 21 dB minimum, 28 dB typical
• LO-IF isolation — 27 dB minimum, 37 dB typical
• RF-IF isolation — 12 dB minimum, 18 dB typical
The MH203A
Product specifications include:
• RF frequency range — 800 to 960 MHz
• LO frequency range — 1000 to 1310 MHz
• IF frequency range — 200 to 350 MHz
• SSB conversion loss — 7.3 dB typical, 8.5 dB maximum
• Noise figure — 7.8 dB
• Input IP3 — +28 dBm minimum, +31.5 typical
• Input IP3 — +30 dBm minimum, +34 dBm typical
• Input P1dB — +17.5 dBm typical
• LO-RF isolation — 25 dB minimum, 30 dB typical
• LO-IF isolation — 50 dB minimum, 60 dB typical
• RF-IF isolation — 25 dB typical
Absolute Maximum Rating
Operating case temperature for the devices is – 40° C to +85° C and storage temperature is – 65° C to +100° C. LO Power is +20 dBm and input IF/RF power is +20 dBm.
These devices use patented techniques to realize +34 dBm Input IP3 at an LO drive level of +17 dBm when used in transceiver applications as an upconverter or a downconverter. This single monolithic integrated circuit series does not require any external baluns or bias elements. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in 3G UMTS systems.
