In my schematics GaAs SPDT switch is used to feed two ICs in turn from single signal source. Switching between two signal destinations is made by applying opposite voltages to two SPDT control pins - A and B. According to datasheet voltages on control pins are always opposite - and it is obviously from typical reflective-short GaAs SPDT schematics (picture below).
But sometimes I need to feed two destinations of signal simultaneously. Could I use reflictive-open GaAs SPDT and apply equal ON-voltage to control pins (V1 and V2 at picture) to split input signal between outputs? In reflective-open SPDT Q3 and Q4 don't exist, so what could possibly go wrong?
If such using of SPDT is forbidden, how to solve this problem?
