GENERAL DESCRIPTION
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, con-

verted 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.
