GENERAL DESCRIPTION
The HMC1094 logarithmic detector converts RF signals at its verted into the voltage domain, and buffered to drive the input to a proportional dc voltage at its output. The HMC1094 LOGOUT output. employs successive compression topology that delivers high The HMC1094 provides a nominal logarithmic slope of 18 mV/dB dynamic range over a wide input frequency range. and an intercept of −113 dBm at 23 GHz. Ideal as a log detector As the input power is increased, successive amplifiers move into for high volume microwave radio and VSAT applications, the saturation one by one, creating an approximation of the logarithm HMC1094 is housed in a compact 3 mm ×3 mm RoHS function. The output of a series of detectors is summed, con- compliant SMT plastic package.
