For best results, the cable must be directly soldered to the PCB. The circuit should be installed near the antenna and housed in a water proofed case. The power supply for this uhf tv antenna ...

For example, test data on two amplifier circuits presented here demonstrate that a considerable reduction in input current and input capacitance can be achieved using a combination of off-the-shelf ...

But to make that measurement you need an amplifier circuit designed for the thermocouple ... pot as well (and a calibration procedure.). The PCB layers are shown below and I can make the Gerbers ...

Without the JFET, the input capacitance is the diode capacitance plus the amplifier input capacitance plus any stray capacitance on your printed-circuit-board (PCB) layout. The 3000-pF diode ...

Don’t design your own; grab cheap and tiny RF amplifier modules and put them on a PCB that fits your needs. These are the grandchildren of the old mini circuits modules that were popular among ...
