Hittite’s HMC7447 is a high-performance E-band MMIC power detector designed to operate over the 71 to 86 GHz frequency range. It 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 76 GHz band and the 81 to 86 GHz band. It also provides desirable repeatability and performance over varying temperature and output load variations.
The chip may be interfaced to an op-amp circuit to achieve a slope of 20 mV/dB at the minimum detector input power level.
