TEKBOX TBSWR-60K500 High Power VSWR Bridge
Introduction
The TBSWR-60K500 high power VSWR – bridge is designed for forward / reverse power measurement in EMC immunity test setups with BCI probes (Substitution Method) and general high power applications in the HF and VHF range. The bridge combines the wide frequency range and directivity of a directional bridge and the low insertion loss and power handling capability of a directional coupler.
The TBSWR-60K500 is characterized in the frequency range from 60 kHz to 500
MHz. The high power handling capability of up to 200W allows inline RF power
measurements, and a variety of other applications. The insertion loss over the
frequency range is typically between 0.15 and 0.6 dB, which is significantly
smaller than the average 7 dB associated with VSWR – bridges.
