Variable Gain Amplifier AVG1012

Sanland’s AVG1012 is a variable Gain Amplifier with Attenuator. The Amplifier has high linearity achieved through the use of 0.5um GaAs Enhancement-mode pHEMT process. It is housed in a miniature 4.0 x 4.0 mm 24-pin Quad-Flat-Non-Lead (QFN) package. It is designed for optimum use from 0.05GHz up to 1018MHz. The compact footprint and low profile coupled with high gain and high linearity make the AVG1012 an ideal choice as a amplifier for CATV network and FTTH network.
