KRYTAR, Inc. Bias Tee KBT010180 KBT010180

KRYTAR has developed a line of Bias Tees offering ultra-broadband control solutions with coverage of multiple microwave bands, from 0.5 to 40 GHz. KRYTAR Bias Tees are the ideal choice for powering remote control of pre-amplifiers or low-noise amplifiers (LNAs) in antennas, controlling remote DC signals and testing of many RF applications. The unique rugged stripline design provides high current handling with high power at frequency and excellent isolation. KRYTAR’s Bias Tee Model KBT010180 offers superior performance ratings including: Operating Frequency range from 1.0 to 18.0 GHz (L thru Ku-Bands); VSWR: 1.65, Insertion Loss <3.9 dB, Min., Isolation of 11 dB, Min., Power Rating is 20 Watts, DC Voltage is 50 Max., and DC Current is 1.5 Amps Max. Standard connectors are SMA Female (optional Type-N) and Operating temperature is -54° to 85° C. Properties that are important to a Bias Tee are RF bandwidth, insertion loss and mismatch at the two RF ports, the maximum DC current, and video bandwidth of the DC port. Connectorized Bias Tees are used in a variety of applications, but are generally used in the transmission line to send the DC and radio signals over the same coaxial cable that is being used to transmit RF signals. One of the prime applications of a RF and Microwave 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. This can be done in the lab for system-level testing. Bias Tees are also used to provide DC power, to power amplifiers mounted on the top a communications tower in close proximity to the antenna. A bias tee can also be used to combine the DC power with a AC/RF signal to provide power to other devices, connected to an antenna. The critical key parameters for the selection of a bias tee are current and voltage requirements, size, cost and a reputable manufacturer in the RF/Microwave community. KRYTAR offers complete engineering services for custom designs that meet or exceed critical performance and/or packaging specifications.
