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-
Rev. A
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.

The circuit board used in the application uses RF circuit design
techniques. Signal lines should have 50 Ω impedance whereas
the package ground leads and exposed paddle should be
connected directly to the ground plane similar to that shown in
Figure 21. Use a sufficient number of via holes to connect the
top and bottom ground planes.
