New Tekbox VSWR Bridges / Directional Couplers
The recently introduced Tekbox VSWR bridges combine the wide frequency range and directivity of a directional bridge and the low insertion loss and power handling capability of a directional coupler. The VSWR bridges are designed for forward / reverse power measurement in EMC immunity test setups and general applications in the HF and VHF rangeVSWR Bridges
