Introduction

The HMC1094 logarithmic detector converts RF signals at its input to a proportional dc voltage at its output. The HMC1094 employs successive compression topology that 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 LOGOUT output. The HMC1094 provides a nominal logarithmic slope of 18 mV/dB and an intercept of -113 dBm at 23 GHz. Ideal as a log detector for high volume microwave radio and VSAT applications, the HMC1094 is housed in a compact 3 mm×3 mm RoHS compliant SMT plastic package.
