Linear mixers

Hittite has introduced two linear MMIC mixers with integrated LO amplifiers for mobile/PCS/3G, broadband, WiBro and WiMAX applications from 0.4 to 4.0 GHz.

The HMC585MS8G(E) is a high IP3 GaAs MMIC mixer with integrated LO amplifier which operates from 400 to 650 MHz, and features high input IP3 of +33 dBm, while requiring only 0 dBm of LO drive. The mixer operates with LO frequencies from 300 to 750 MHz making it suitable for high side and low side LO frequency plans.

It is housed in an RoHS-compliant MSOP8G 'E' SMT package and shares a common pinout with the HMC483MS8G(E) and the HMC485MS8G(E) family of high IP3 mixers which cover frequencies from 0.7 to 2.4 GHz.

The HMC215LP4(E) is a double-balanced GaAs MMIC mixer with integrated LO amplifier which is rated from 1.7 to 4.0 GHz, and features high LO to RF isolation of 32 dB, low conversion loss of 8 dB, and high input IP3 of +25 dBm.

This wideband mixer is housed in a RoHS-compliant leadless 4 x 4 mm QFN 'E' SMT package and shares a common pinout with the HMC551LP4(E) and the HMC552LP4(E) family of double balanced mixers with integrated LO amplifiers which operate from 0.8 to 3.0 GHz.

Both devices operate from a single +5 V supply and their passive mixer topologies make them suitable for upconversion and downconversion applications.
