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.
