Directional Detectors Reach 30 GHz

 Directional detectors simplify power monitoring in various systems through 30 GHz.

Surface-mount directional detectors from M/A-COM Technology Solutions, Inc. (M/A-COM Tech) include models suitable for power-monitoring applications through 30 GHz in commercial radios and military radar systems. Based on GaAs process technology and supplied in miniature, surface-mount 1.5 x 1.2 mm lead-free plastic packages, the directional detectors can be mounted with standard pick-and-place automated assembly equipment. Requiring less than 0.5-mA bias current, the detector line includes models MACP-010561, MACP-010562, and MACP-010563. Model MACP-010561 exhibits 0.25-dB insertion loss from 2 to 6 GHz with 16-dB directivity, 23-dB input return loss, and 24-dB output return loss. It operates with 100-mV DC offset and 0.3-V bias voltages. Model MACP-010562 operates from 6 to 18 GHz with 0.30-dB insertion loss and 19-dB directivity. It achieves 18-dB input return loss and 20-dB output return loss with100-mV DC offset and 0.3-V bias voltages. Model MACP-010563 is designed for use from 10 to 30 GHz, and provides 0.50-dB insertion loss and 16-dB directivity. It boasts16-dB input return loss and 17.5-dB output return loss, with 100-mV DC offset and 0.3-V bias voltages.
