The HMC813 and the HMC813LC4B successive-detection log video amplifiers (SDLVAs) with a limited RF output feature operate over the 1 to 26-GHz and 1 to 20 GHz-frequency ranges, respectively. The parts suit designers with space- and power-constrained applications including EW and ELINT receivers, DF radar, ECM, IFM systems, and missile guidance. The devices also suit high-speed channelized systems that require improved ESD performance. These SDLVAs employ a successive-compression topology, which delivers a high logging range of 55 dB and provides a nominal log video output slope of 15 mV/dB.
Both devices can processi RF pulses with amplitudes from –53 to 7 dBm with less than 10 ns rise/fall times, and with recovery times of less than 20 ns. These SDLVAs exhibit frequency flatness of better than ±1.5 dB at –25 dBm input power, while logarithmic linearity is better than ±0.5 dB over the full –55° to 85°C operating temperature range. They consume less than 153 mA from a single 3.3V supply. Available in die and ceramic 4×4 mm SMT formats, the parts feature power limiter circuitry at their RF outputs and carry a class 1A ESD rating (250V HBM).(Contact company for pricing — available now.)
