Hittite Microwave has announced a new E-Band MMIC power detector that 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.
This detector is available in die format and complements Hittite’s E-Band product offering, specially the HMC-APH633 and HMC-APH634 E-band power amplifiers. The HMC7447 power detector features I/Os that are internally matched to 50 Ohms and require no external matching components. Die samples are available from stock and can be ordered from Hittite.
