ADI HMC662LP3E

8 ГГц ~ 30 ГГц

Overview

The HMC662LP3E Logarithmic Detector converts RF signals at its input, to a proportional DC voltage at its output. The HMC662LP3E 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 square law detectors is summed, converted into the voltage domain and buffered to drive the LOG OUT output. The HMC662LP3E provides a nominal logarithmic slope of +13 mV/dB and an intercept of -127 dBm at 18 GHz. Ideal as a log detector for high volume microwave radio and VSAT applications, the HMC662LP3E is housed in a compact 3x3 mm RoHS compliant SMT plastic package.
