Comprehensive selection of 2-way through 16-way power divider/combiners in N-Type, SMA, BNC, TNC and 7/16 DIN connector sytles for frequencies from 0.4 to 18.0 GHz for narrow, octave, dual and multi-octave band applicaitons.
Directional couplers are used in a wide variety of applications and can satisfy almost any requirement for ampling incident and reflected microwave power conveniently and accurately with minimal disturbance to the transmission line. Some general applications for directional couplers include line monitoring, power measurements and load source isolators.
Attenuators aer used in a wide variety of applications and can satisfy almost any requirement where a reduction in power is needed. Attenuators are used to extend the dynamic range of devices such as power meters and amplifiers, reduce signal levels to detectors, match circuits and are used daily in lab applications to aid in product design. Attenuators are also used to balance out transmission lines that otherwise would have unequal signal levels.
Termination, or loads, are matched to 50 ohms characteristic impedance. Matched loads provide a termination designed to absorb all the incident power with very little reflection, effectively terminating the line or port in its characteristic impedance. Terminations are used in a wide variety of measurement systems; any port of a multi-port microwave device that is not involved in the measurement should be terminated in its characteristic impedance in order to ensure an accurate measurement. Terminations are also used in devices such as directional couplers and isolators. High power versions are used in transmitter applicaitons as dummy loads.
An RF isolator is a two-port passive device made of magnets and ferrite material which is used to protect other RF components from excessive signal reflection, while and RF circulator is a three-port passive device used to control the direction of signal flow in a circuit.
A 3db, 90° hybrid coupler is a four-port device that is used either to equally split an input signal with a resultant 90° phase shift between output signals or to combine two signals while maintaining high isolation between them.
