The new KRYTAR line of bias tees offers broadband control solutions with coverage within multiple frequencies from 0.5 to 40 GHz. These bias tees target applications like powering remote control of pre-amplifiers or LNAs in antennas, controlling remote DC signals and testing of many RF applications. A key application for a bias tee is to inject DC currents or voltages into RF and microwave circuits without affecting the RF signal passing through the main transmission line. Bias tees are also used to provide DC power to power amplifiers and other devices mounted at the top of a communications tower near the antenna.

The new KRYTAR family of 12 coaxial connectorized bias tees are rugged, compact designs offering the following performance:

Insertion loss (dB maximum): less than 1.4 dB to less than 6.0 dB; isolation (dB minimum): 10 to 18 dB; VSWR (maximum): 1.5:1 to 1.9:1; power (W maximum): 20 DC voltage (V maximum): 36 to 60; DC current (A maximum): 1.0 to 2.0.

The bias tees are available with standard SMA female or 2.4 mm female connectors, for higher frequencies. KRYTAR also offers complete engineering services for custom designs that meet or exceed critical performance and/or packaging specifications.

For nearly 50 years, KRYTAR, Inc. has specialized in the design and manufacture of broadband mmWave, microwave and RF components and test equipment for both commercial and military applications. The KRYTAR product line covers DC to 110 GHz and it includes directional couplers, directional detectors, 3 dB hybrids, MLDD power dividers, detectors, terminations, coaxial adapters and Butler matrices. KRYTAR microwave components are manufactured in full compliance with the EU RoHS-6 environmental requirements.
