i am designing a stepped attenuator using pin diode as a switch in microwave office. i am having difficulty in using pin diode as a switch. i knw it is operate in forward bias and open in reverse bias. if i am giving a rf signal between 300 Mhz to 3 Ghz then how can i switch it to reverse bias? secondly there is something called bias wat is it?
