-55 to +85° C Operating Temperature Functional Diagram General Description
The HMC813 is a Successive Detection Log Video
Amplifier (SDLVA) With Limited RF which operates
from 1 to 26 GHz. The HMC813 provides a logging
range of 55 dB. This device offers typical fast rise/fall
times of 4/10 ns. The HMC813 log video output slope is
typically 14.5 mV/dB. Maximum recovery times are less
than 20 ns. Ideal for high speed channelized receiver
applications, the HMC813 operates from a single
+3.3 V supply, and consumes only 150 mA. All data
shown herein is measured with the chip in a 50 Ohm
environment and contacted with RF probes. Electrical Specifications, TA = +25 °C, Vcc1 = Vcc2 = Vcc3 = Vcc4 = 3.3V [1]
