This 80's circuit can be implemented with modern equivalent FETs with lower on resistance. The attenuation is 80 dB at 100MHz.
We found this circuit in the Radio Electronics magazine of February 1993. The main integrated...
The instrument is a common multimeter on the lower voltage scale. The FET can be BF245 or MPF102. The...
This circuit is from General Electric documentation from 1970. The transistors can be of...
