TBSWR-600K700

High Power VSWR Bridge

The Tekbox TBSWR-600K700 is a high-power VSWR (Voltage Standing Wave Ratio) bridge designed for forward and reverse RF power measurements in EMC immunity test setups — especially with BCI probes (Substitution Method) — and general high-power applications in the HF and VHF frequency ranges. It combines the wide frequency range and strong directivity of a directional bridge with the low insertion loss and power handling capability of a directional coupler.

Features

Key capabilities and advantages

  • Purpose-built for forward/reverse power measurement in RF and EMC tests.
  • Wide frequency coverage: characterized from 200 kHz to 700 MHz.
  • Good directivity for accurate measurement separation of forward and reflected power.
  • Low insertion loss (typically < 0.7–1.5 dB) across its operating band.
  • Suitable for demanding RF setups Compact design with standard RF
  • Ideal for EMC immunity tests, HF/VHF RF measurement setups, and general power diagnostics.
