TinySA - Spectrum Analyzer
- Maximum input level
- 0 dBm = 1 mW
- dBm = 10*LOG(milliwatts)
- -10 dBm = 0.1 mW
- +10dBm = 10 mW
- +20dBm = 1000 mW
- 3.3V at 50 Ohm = 0.2178W
- 217.8 mW = 23.4 dBm
- tinySA wiki
Attenuators
30 dBm Attenuator
- Standard 10% resistor values
- R2 = 4 paralleled 240 Ohm 1/4W resistors
