- Try something else..
- Use a SBL-1 or similar. DBM. it is a BiDi device
- Connect one?? RF port to signal INput and second to OUTput or
other way.
- Feed a DC control voltage through a resistor to the IF port. Try with
1-10K.
- Vary the voltage and see the signal level change. The behavior is
opposite
- of the varicap control voltage.
- We can use this for AGC and ALC in either direction.
- WOW !!! I had never thought about it ! it's almost brilliant! with a
little time, as soon as the job allows me, I could try!
- Thanks Raj ... it's as simple as it is brilliant!
