HST136S GaAs Power Attenuator IC

As the leading manufacture and supplier of GaAs power IC GaN power IC, Homray Semiconductor Technology offer GaAs digital attenuators. The HST136S is a 3-bit GaAs pHEMT digital attenuator. Convering DC to 18GHz, the insertion loss is less than 2dB and the attenuator bit values are 5 dB, 10dB, 20dB for a total attenuator of 35dB. RMS of attenuation accuracy is excellent at 1dB. The attenuator operates using a negative control voltage of 0/-5V to select each attenuation state and requires no bias supply.
