CASE ANALYSIS
Scenario
A satellite installer inserts this passive detector in the LNB coax run to align the dish by peaking the IF signal level on an analog meter while adjusting the sensitivity control.
Key decisions
- Use a 1N4148 RF detector diode with a 10 nF coupling capacitor to rectify the IF without loading the LNB line.
- Use a 10 kΩ sensitivity resistor to scale the rectified DC into the 1 kΩ meter load for a visible deflection.
- Represent the analog meter as a 1 kΩ load resistor for a clean two-terminal schematic symbol.
When to reuse this
Reuse this netlist for any simple satellite finder or signal strength indicator where an analog meter and a single sensitivity control are required.
