MACP-01057x Directional Power Detectors MACOM MACP-01057x Directional Power Detectors are small, easy-to-use, broadband detectors that feature integrated low-loss directional couplers and built-in temperature compensation circuits. The MACP-01057x series monitors the power of a signal traveling in a specific direction along a transmission line. The detectors are housed in a miniature, surface-mount, lead-free plastic package. MACOM MACP-01057x Directional Power Detectors require only a small amount of bias for proper performance, and the total bias current is less than 0.5mA.
