HMC7447 power detector

Hittite Microwave, the supplier of complete MMIC based solutions for communication & military markets, has announced a new E-Band MMIC power detector that it says is ideal 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. Ideal for monitoring transmitter operation or enabling closed loop transmitter output power, the detector exhibits excellent sensitivity and a frequency response of ±0.2 dB over the 71 to 86 GHz frequency band.

The HMC7447 power detector also provides excellent 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.
