HMC662LP3E

HMC662LP3E is a logarithmic detector convert RF signals at its input, to a proportional DC voltage at its output. This employs successive compression topology which delivers high dynamic range over a wide input frequency range. As the input power is increased, successive amplifiers move into saturation one by one creating an approximation of the logarithm function. The output of a series of detectors is summed, converted into the voltage domain and buffered to drive the LOG OUT output. Typical application includes point-to-point microwave radio, VSAT, wideband power monitoring, receiver signal strength indication (RSSI, test & measurement.
