IMK Series Resistive Coupler

Broadband Low-Loss Device
IMK Series Resistive Couplers provide the sensing function over a broad range of frequencies in a compact, easy to use component. Insertion loss is comparable to the more complicated frequency sensitive couplers.
Like IMS attenuators, the IMK Series is engineered to optimize performance in two ways:
1) Resistive areas are constant and are specified for the lowest dB value ensuring that all couplers easily handle the incident RF power.
2) High inductive lines are specified to minimize ground path leakage and maintain low through loss.
