Scientific Microwave Released WRD750-WR75 Waveguide Isolator
The new ferrite-based assembly protects high-power microwave systems by managing signal flow across the Ku-band.
Updated on Sept. 23, 2026 in Semiconductors
Scientific Microwave Corporation has launched the WRD750-WR75, a waveguide isolator assembly engineered to protect microwave sources and amplifiers from reflected power. This device is now available for integration into systems requiring stable performance in the 13.5 to 15.0 GHz frequency range.
Why it matters
By isolating sensitive microwave components from reflected energy, this assembly ensures the longevity and operational stability of high-frequency power systems. It addresses the growing need for robust signal management in demanding thermal and power-intensive environments.
The unit provides over 12 dB of isolation with an insertion loss below 1 dB. It features an input VSWR of 2.0:1 across its test band and 1.5:1 in the operating band, while weighing 600 g and maintaining performance from -55°C to +75°C.
The players
Scientific Microwave Corporation
A developer of specialized microwave components including isolators and circulators designed for high-power radio frequency applications.
The details
The device employs ferrite-based technology, which creates a non-reciprocal path that allows microwave signals to pass in one direction while suppressing them in the other. It is housed in an aluminum 6061 structure, a common aerospace-grade alloy known for its strength-to-weight ratio. The assembly uses a TNC female input and a WR75 waveguide output to bridge signal connections between different interface types.
