Abstract
An embedding absorptive single-pole-eight-throw (SP8T) switch circuit structure is proposed. The absorptive SP8T switch based on PIN diode ON/OFF characteristic has been designed over a frequency range 14 GHz to 18 GHz with lower transmission loss less 3.9 dB, output return-loss more 10 dB at ON state, and isolation more 60 dB, input/output return-loss more 12 dB at OFF state. Comparing with conventional absorptive switch circuit, the SP8T switch posses the feature with transmission loss less at ON state and output reflection less at OFF state, because absorption resistance in the circuit is embedded in ground board under the substrate. More importantly, the embedding absorptive structure can be applied to absorptive attenuators and absorptive limiters.关键词
