Top 5 Hybrid Coupler Producers

Hybrid couplers are often used to add or split power signals coming in, but they can also be used for antenna beam-forming networks. These passive devices are made to split a signal coming in and send it to each output at the same time, with a certain amount of time between each output.

Most Hybrid Coupler use microstrip or stripline technology to move the line segments so that each output port is 90 or 180 degrees away from the next. This shift induces a phase difference between the outputs.

1. KRYTAR

KRYTAR is a company specializing in the design and manufacture of ultra-broadband microwave components and test equipment. They have a wide range of products, including directional couplers, detectors, 3 dB hybrids, power divider, and coaxial adapters.

Their hybrid couplers are designed for wideband applications such as electronic warfare (EW), commercial wireless, SATCOM, radar, signal monitoring and measurement, antenna beam-forming networks, and EMC testing environments. They have excellent performance ratings for insertion loss, coupling, directivity, and isolation in a compact package.

They have a variety of different types of hybrid couplers, but the most common is a 90-degree double-arrow construction hybrid coupler that maintains an even 180-degree phase relationship at all frequencies. The couplers are constructed with a three-layer stripline construction in which couple of lines are etched on opposite sides of a thin copper circuit board sandwiched between two equally thick dielectric boards.

The company also offers a line of 180-degree hybrids. These hybrids have a double-arrow construction in which two asymmetric, tapered-line directional couplers are cascaded to maintain an even 180-degree phase relationship between channels.

These couplers are a good choice for applications that require very tight amplitude imbalance specifications, as well as phase imbalance specifications. They are also very useful for reducing noise in amplifiers via feedback-combining techniques or merging multiple signals from arrays.

Another advantage of these hybrids is that they can be used to delay an output signal. The signal at the outputs lags by about 1/4 of the period when using a 90-degree hybrid, while it lags by about half of the period when using a 180-degree hybrid.

KRYTAR is also a good choice for companies that make hybrid couplers for the military and need to make them to strict standards.  They offer a complete engineering service for custom designs that can meet critical performance and packaging requirements.

5. Clear Microwave

Clear Microwave manufactures an extensive range of RF and microwave couplers, including hybrid couplers. Their products are well suited for applications such as cellular backhaul, point-to-point radio, and radar. The company has recently added 21 new hybrid coupler models that offer a wide range of operating frequencies, high power handling capabilities, 90-degree or 180-degree output phase shifts, and low return loss.

The company's hybrid couplers are based on ridge gap waveguide technology, which allows them to be reconfigurable. The ridges in between the couplers guide the wave, providing isolation between the paths and a stable frequency response. The technology is particularly useful for guiding waveguides in millimeter and submillimeter wavelength bands, but the bandwidth limit is prohibitive, making it less suitable for high-frequency applications.

This microwave delivered fluffy potatoes and fully cooked ready meals, as well as reheating and defrosting mince, in all of our tests. However, its controls took a bit of getting used to, and its interior lighting was a little too dim. Fortunately, it offers the option to turn off the display when not in use or muffle the beeps. It also has a reasonable 20-liter capacity, five power levels, and a range of automatic programs.
