Various aspects of the technology include an integrated circuit device comprising a compound semiconductor layer and a plurality of input, switch, and ground ohmic metal fingers fabricated on the compound semiconductor layer in a repeating sequence. A control gate may be disposed between each input finger and adjacent switch finger, and a sync gate may be disposed between each ground finger and adjacent switch finger. A sync gate and a control gate may be disposed adjacent each switch finger. The device further includes a plurality of control gate pads, each control gate pad at an end of two control gates, and a control gate pad at opposite ends of each control gate, and a plurality of sync gate pads, each sync gate pad at an end of two sync gates, and a sync gate pad at opposite ends of each sync gate. |
