I'm designing a transmit/receive switch for an antenna using a PIN diode.
The PIN diode I'm using is UM7512 make: Microsemi.
I need to switch between -400V (off) to +5V (on). The switching time should be 50usec.
On current is 200mA. Off current is 1-2 mA.
I need a reference circuit idea or design about this requirement.
How do I approach this design?
