Now i need a high-power T-R switch that can switch state in two
microseconds. Drive outputs: +12 volts(current ,0.5 ampers) , +700
volts , -12volts(-0.5 ampers), -12 volts. Tx path may stand 600
watts
(peak). I want to use PIN driver IC,but don't find IC that may output
+700 volt. So i have to design the switch by myself.
I am going to employ discrete MOSFET as driver . Input to the
MOSFET is TTL logic.
some specification of my switch is :
working frequency band : 3 - 30 MHz
T - R isolation : > -80 dB (when transmitting)
Anyone ever do this? Can i get so fast speed(< 2 microseconds)?
Would you give me some suggestions? Any help will be appreciated!
