Example 4-5-1: Directional Coupler • A symmetric directional coupler with infinite directivity and a forward attenuation of 20 dB is used to monitor the power delivered to a load ZI. Bolometer1 introduces a VSWR of 2.0 on arm 4; bolometer 2 is matched to arm 3. If Generator 11 20 dB 12 SWR = 2.0 31 14 Bolometer 2 Bolometer I Figure 4-5-4 Power measurements by directional coupler.
