The MACP-010561 belongs to a series of small, easy-to-use, broadband, directional detectors. With integrated low loss directional couplers and built-in temperature compensation circuits, these detectors provide an easy way to monitor the power of a signal travelling in a specific direction along a transmission line. Detectors are housed in a miniature, surface mount, lead less plastic package. They require a small amount of bias for proper performance. The total bias current is less than 0.5 mA.
