Abstract:
In this study, S-band microstrip stub switch, using PIN diode such as HP 5082-3005 series for the switching element, is designed in the SPST configuration at the central frequency of 2.5 GHz. The design procedure for multiport switches is given. The theory of PIN diode and microstrip line are presented for the de.sign of the microwave diode switch. Different types of swi tches are investigate·d. An experimental results are reported for the purpose of supporting theory. A microstrip line stub switch has been constructed in which PIN diode provides 24 dB isolation and 1.5 dB insertion loss at the central frequency of 2.65 GHz.
