High Power Coaxial Terminations
Spectrum Control’s ultra-low VSWR (1.1:1) coaxial dummy loads deliver industry-leading performance up to 6 GHz. These RF terminations handle up to 1000 watts and operate across standard MIL temperature ranges from -65°C to +125°C. Designed for rugged, high-performance applications, they offer exceptional reflection performance and VSWR, with a wide range of high-power models available.
With incident power ranging from 100 to 1000 watts (up to 10 kW peak), efficient heat dissipation is critical. Spectrum Control’s high-power terminations provide both convection and conduction cooling options, with power handling linearly derated to 100 watts at +125°C.
With incident power ranging from 100 to 1000 watts (up to 10 kW peak), efficient heat dissipation is critical. Poor heat sinking can cause resistance shifts, degrading VSWR and potentially leading to permanent component failure. To perform effectively, a high-power 50-ohm RF load must provide repeatable performance, flat frequency response, and wideband stability across the operating band.
Low VSWR (1.1:1) is essential for high-power RF terminations, ensuring a reflection-free match that absorbs energy without sending it back into the signal path. Poor VSWR can distort waveform amplitude, introduce phase shifts, and create standing waves that stress upstream components or force amplifiers beyond their intended limits. Spectrum Control’s ultra-low VSWR (1.1:1) terminations maintain phase linearity and spectral purity up to 6 GHz. Consistent VSWR across frequency is key to minimizing distortion, as unexpected reflections can reshape signals and degrade overall system performance.
