A CMOS 65 nm DC-17 GHz single pole eight throw switch for 8 GHz radar impulse communication

A DC-17 GHz single pole eight throw (SP8T) switching matrix has been developed on standard 65 nm CMOS process for the first time for impulse radar communication. The measured input and output matching bandwidth are 0–17 GHz where both the input and output return losses are greater than 10 dB. Measured average insertion loss from Tx port to different output ports are 3.6 dB, 6 dB and 10 dB at 3 GHz, 10 GHz and 17 GHz, respectively, with 1.2 mW power consumption. The switch is implemented on printed circuit board with flip chip mounting. A 0–20 GHz matching bandwidth was obtained using quarter wavelength microstripline and a 0.1mm thickness Magatron 6 board. The time domain wideband characteristics of the switch was tested with 8 GHz Gaussian monocycle pulse (GMP).
