We have a vast selection of instrumentation-grade waveguide RF directional couplers on offer, including standard and split block designs. With a typical high directivity of 30 dB and an insertion loss as low as 0.6 dB, our RF/microwave and millimeter wave waveguide couplers supply Voltage Standing Wave Ratio (VSWR) as low as 1.2:1 and offer an operating frequency from 18 GHz up to 110 GHz. For added reliability and durability, our directional couplers for waveguide feature bodies and flanges made of brass copper with gold plating.
They are available in various sizes - from WR-42 (K-band) to WR-10 (W-band). They also have 10 dB and 20 dB coupling values and come in seven different frequency bands, including K, Ka, Q, U, V, E and W. Depending on your project requirement, we also stock E bend and H bend configurations. These are all in stock and ready to ship immediately.
Our instrumentation-grade waveguide directional couplers, such as the SMW42HC001-20, SMW28HC001-20, SMW19EC001-20 and SMW12EC001-10, come in handy during test setups where power reflection measurements, that involve power sampling and frequency monitoring with minimal signal loss to the main transmission path, are required. Typical scenarios include test benches, radar, satellite, microwave radio, attenuation and power measurements and source leveling.
All our waveguide directional couplers are in stock and available for same-day shipping. terminated with MMBX connectors. With low or no minimum order quantities, they are ready to ship at once.
