Abstract

In this paper, we present a low-voltage highspeed antimonide-based compound semiconductor (ABCS) high electron-mobility transistor (HEMT) monolithic microwave integrated circuit (MMIC) process and its single-pole double-throw (SPDT) broadband switch application. The measured 3-dB bandwidth of the proposed SPDT switch is from dc to 30 GHz. The switch features an insertion loss of less than 4 dB, and an isolation of greater than 18 dB between 10 MHz and 30 GHz. The measured input 1 dB compression point (P1dB) and third-order intercept point (IP3) at 100 MHz are 12.5 and 27 dBm, respectively. The chip size of the proposed switch is 0.75 × 0.58 mm2. These results demonstrate the outstanding potential of ABCS HEMT technology for low voltage switch applications.
