E-band MMIC power detector for communications, test, sensors, and RF detection introduced by Hittite

CHELMSFORD, Mass., 13 Jan. 2014. Hittite Microwave Corp. in Chelmsford, Mass., is introducing the HMC7447 E-band MMIC power detector for RF and microwave applications in 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 insertion loss of 0.45 dB and typical input return loss of 19.5 dB.

For monitoring transmitter operation or enabling closed loop transmitter output power, the detector exhibits sensitivity and a frequency response of plus-or-minus 0.2 dB over the 71 to 86 GHz frequency band.

The HMC7447 power detector also provides repeatability and flat performance over varying temperature and output load variations. It 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 has I/Os that are internally matched to 50 Ohms and require no external matching components. Die samples are available from stock.
