| RF Termination |
|
Terminations, or loads, offered by MECA 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
applications as dummy loads. |

When selecting a termination for a given connector style, one must determine the amount of power that needs to be absorbed and the acceptable level of reflection (VSWR) that can be tolerated over the given frequency range. MECA offers a wide selection of terminations from stock ready for your just-in-time shipments. With power ratings from 1 to 500 watts and frequency ranges up to 18 GHz, our terminations are designed to exceed commercial specifications. Custom configurations with different impedance values, frequency ranges, power ratings, package sizes or heat sink profiles and connector styles or plating are also readily available in quantity. Silver-plated connectors available for your PIM concerns. With immediate access to our Application Engineers, you can choose the best product solutions for your specific needs.
