The HMC600LP4(E) logarithmic detector/controller is fabricated in a SiGe BiCMOS process and converts RF signals at its differential input to a proportional output DC voltage. The HMC600LP4 (E) delivers a high ±3 dB dynamic range of up to 75 dB, with accuracy and temperature stability from 50 MHz to 4000 MHz. In logarithmic detection mode, the HMC600LP4(E) provides a nominal logarithmic slope of 19 mV/dB . The RF input is internally matched to 50 Ohms, and the device will operate with a supply voltage range of + 2.7 V to +5.5 V, consuming only 30 mA.
