E-Band MMC power detector operates over 71 to 86GHz frequency range
Hittite Microwave’s new E-Band MMIC power detector is targeted at communications systems, test equipment, sensors and general purpose RF detection over the 71 to 86GHz frequency range. The HMC7447 power detector provides a linear output voltage over a -0.5 to +23.5dBm 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 86GHz frequency band. The 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.
Available in die format, the detector complements Hittite’s E-Band product offering, and can be used in conjunction with the HMC-APH633and HMC-APH634 E-band power amplifiers. The power detector features I/Os that are internally matched to 50 Ohms and require no external matching components.
