Hello !!
Actually m designing switched line phase shifter and switching using PIN diodes(series-shunt config) on 50Ω microstrip, with substrate ε=2.2, h=31mils.
For providing Bias to PIN diodes i have used Radial stub and λ/4 high impedance line.The biasing is such that At the series shunt configuration when series diode is ON, shunt diode OFF. or vice versa. I am simulating in ADS
The problem is that when the series diode is OFF & shunt diode is ON i want to ground the RF signal through Shunt diode path,So how the layout can be.
Looking for Reply.
