AGC1011 Digitally Controlled Variable Gain Amplifier

Sanland’s AGC1011 is a variable Gain Amplifier with digital Attenuator.  The Amplifier has low noise and 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 1.2GHz. The compact footprint and low profile coupled with low noise, high gain and high linearity make the AGC1011 an ideal choice as a low noise amplifier for CATV network and FTTH network.
