Double Channel HEMT's are used as variable resistor elements in a bridged-T attenuator with broadband characteristics (0.5-12GHz), and wide dynamic range (12-16dB). A small insertion loss (2.8dB minimum) is obtained with the help of the heterojunction approach which results in smaller ON-channel resistances than MESFET technology.
