Digitally Controlled VGA · GaAs pHEMT

Digitally Controlled Variable Gain Amplifiers for CATV & FTTH

SANLAND’s AGC1011P combines broadband RF amplification with a digitally controlled attenuator, enabling repeatable gain adjustment through external C1–C5 control inputs.

Built on a 0.5 µm GaAs enhancement-mode pHEMT process, the device offers low noise, high linearity and compact 4 × 4 mm QFN integration for CATV, FTTH and PON / ONU signal paths.
