Low Noise Active Mixer, 4 – 23 GHz

Plastic packaged low noise active mixer. It is used for down frequency conversion and has an ultrawide band IF of over 6 GHz. The mixer integrates an FET gain element with LO and RF driving the same pin. The transconductance mixing allows very low noise figure for an active mixer. This mixer can be used for either lower sideband (LSB) or upper sideband (USB) mixing. This mixer allows very low LO drive (< 0 dBm) and low DC bias. Typically the IF pin is 3v at 15 mA typical and the VG pin is 0.9v. Mixer is housed in a lead-free ultra small 1.5 x 1.2 mm TDFN surface mount plastic package. The Mixer is fabricated using a GaAs process which features full passivation for increased performance and reliability.
