Power Detector Serves Test and Sensor Markets

December 31, 2013. Hittite Microwave Corp. has announced a new E-Band MMIC power detector that is suitable for communications systems, test equipment, sensors, and general-purpose RF detection over the 71- to 86-GHz frequency range.

The HMC7447 power detector provides a linear output voltage over a -0.5- to +23.5-dBm input power range with low insertion loss of 0.45 dB and typical input return loss of only 19.5 dB. Suitable for monitoring transmitter operation or enabling closed-loop transmitter output power, the detector exhibits a frequency response of ±0.2 dB over the 71- to 86-GHz frequency band. The HMC7447 power detector may be interfaced to an op-amp circuit to achieve a slope of 20 mV/dB at the minimum detector input power level.

Available in die format, the HMC7447 complements Hittite’s E-Band product offering and can be used in conjunction with the HMC-APH633 and HMC-APH634 E-band power amplifiers. The HMC7447 power detector features I/Os that are internally matched to 50 Ω and require no external matching components. Die samples are available from stock and can be ordered via the company's e-commerce site or via direct purchase order.
