F.1.1 Input related parameters
F.1.1.1 Frequency range
1) If a Down-Converter accommodates various bands specify FL & FH for each band.
2) Example low frequencies are 100 MHz and 1 GHz.
3) Example high frequencies are 6 GHz, 26.5 GHz.
F.1.1.2 Return loss (RL)
RL = -20 Log (Vr/Vi); where Vr is the reflected power and Vi represents the transmitted or incident power
1) A related parameter is voltage standing wave ratio (VSWR). VSWR is the ratio between the sum and difference of an incident and its associated reflected voltage wave. VSWR ratios may range from 1 to infinity.
2) The ratio is -20 Log (Vr/Vi).
