RF sensor relay switch
It will probably work a lot better like this.

Thanks you very much JimB..
I will test it... Oh if i not used TIP 92 ( TR2 ) , but will used 2N3904 for ( TR2 ) it will work ?? I dont know about bias on TR2 if used 2N3904 and it will can carry switch 3 relay ??
This supply 5V will come from 12-13.8V regulator 12-15A into this IC1 regulate 5V ( this you think it will not damage the IC1 ??) and after out from IC1 it have 5V this +5V will not damaged the relay ?? because relay coil only 178 ohm.. ( i will used RF relay HF3S AXICOM Relay )
- This relay spec 5 Vdc , Coil power 140mW , Coil resistance 178Ω :
Number of contacts and type 1 changeover (SPDT)
Contact material Silver, gold-covered
Limiting continuous current at max. ambient temperature 2 A
Maximum switching current 2 A
Maximum swichting voltage 220 Vdc / 250 Vac
Maximum switching capacity 60 W / 62.5 VA / 50 W (2.5 GHz)
Initial contact resistance at 10 mA / 20 mV < 100 mΩ
Mechanical endurance 107 operations
Max. Continuous RF-power 100 W @ 3 GHz (with appropriate cooling, only)
150 W @ 2 GHz (with appropriate cooling, only)
Peak RF-power 300 W (with appropriate cooling, only)
Thanks
