A Novel SiGe PIN Diode SPST Switch for Broadband T/R Module

A novel octagonal SiGe p-type intrinsic n-type (PIN) diode single pole single throw (SPST) switch is first implemented in a standard 0.18-mum SiGe BiCMOS technology. Distinctive radio frequency performance of monolithic silicon PIN diode switch is achieved for broadband applications with improvement of its geometry. Over the 2-16GHz frequency band, the PIN diode SPST switch exhibits an insertion loss of less than 1dB and isolation between 42dB to 19dB. An accurate small signal model of series PIN diode is also presented
