I am trying to think of a simple circuit that drives the control voltages of a SPDT switch. The switch has two control voltages V1 and V2.
State 1: V1 high and V2 low -> RF1 on and RF2 off
State 2: V1 low and V2 high -> RF1 off and RF2 on
State 3: V1 high and V2 high -> RF1 on and RF2 on
State 4: V1 low and V2 low -> RF1 off and RF2 off
The logic voltage level is around 4V. I want to switch between State 1 and State 2 every 50usec or so. Can anyone give me an idea on how to implement this?
I had two ideas. Using a flip-flop or a LM555 timer circuit. Though, I haven't figured out the specifics yet.
