High power terminations, resistors & attenuators


Res-Net offers microwave attenuators, terminations, diode detectors, and resistors for the RF and microwave industries. The microwave attenuators and terminations range from the small flange type to large 2,000 watt power attenuators and/or terminations. The offered products are: 

There are multiple uses for terminations in various RF and Microwave circuits and systems. Typical applications include;

Test Setups and Instrumentation: High power terminations may be used in place of an antenna for testing transmitters, as shown in Fig. 1. The impedance on the terminations can also be changed in order to create a controlled mismatch on the transmission line. This is useful in reflection calibration of reflectometers, or in test setups to reproduce specific characteristics that a system would encounter after installation (transmitter tuning).

Power Dividers and Combiners: Terminations are placed on the isolation port of hybrid and directional couplers to reduce reflections back to the system that could cause degradation in performance, Fig 2.  In Wilkinson type power dividers, terminations are used to terminate unused ports. The optimum design of these circuits requires proper impedance match on all RF ports.
