PI衰減器計算器 (回波) | PI Attenuator Calculator

Calculates the resistor values, attenuation, ’impedance’, reflection coefficient, VSWR and return loss of a Pi attenuator. This can be built into a FLEXI-BOX, and a transmission line PCB is available which easily adapts for this circuit with one simple trimming operation. There is also a selection of suitable RF connectors available.
