TekBox TBSWR-60K500 High Power VSWR Bridge

Overview

The TekBox TBSWR-60K500 is a high-power VSWR bridge designed for forward and reverse power measurements in EMC immunity test setups with BCI probes and general high-power HF and VHF applications. It combines the wide frequency range and directivity of a directional bridge with the low insertion loss and high power handling of a directional coupler, making it ideal for inline RF power measurements. This model extends to lower frequencies (60 kHz) and supports higher power levels than the TBSWR-200K500.

Key Features

• Frequency range: 60 kHz to 500 MHz
• Directivity: >20 dB across frequency range, up to >30 dB in key bands
• Insertion loss: 0.15 to 0.6 dB across frequency range
• Power handling: 200 W CW (60 kHz–200 MHz), 100 W CW (200–500 MHz)
• Impedance: 50 Ω
• RF connectors: N-female through ports, SMA-female coupling ports
• Port matching: >20 dB
• Operating temperature: -20°C to +40°C

Applications

• Forward and reverse power measurement in EMC immunity tests
• BCI probe substitution method measurements
• Extended low-frequency power measurements
• High-power measurement and monitoring in HF and VHF applications
