The HMC1013LP4E successive-detection log video amplifier (SDLVA) operates over the full 0.5 to 18.5-GHz frequency range, extends the dynamic range to 67 dB, and carries a class 1-A ESD rating (250-V HBM). The part convert RF signals at their input to an output voltage that is proportional to the logarithm of the RF input signal amplitude.
Its small size of 4 x 4 mm and performance makes this part suitable for space- and power-constrained applications including EW and ELINT receivers, DF radar, ECM, IFM systems and missile guidance. It employs a successive-compression topology which allows for the processing of high level signals up to 5 dBm. During typical operation, the HMC1013LP4E provides a nominal slope of 15 mV/dB.
The SDLVA can process RF pulses with amplitudes from 62 to 5 dBm with 5-ns rise times, and with less than 40 ns of recovery time. The HMC1013LP4E exhibits frequency flatness of better than ±2 dB, while logarithmic linearity is better than ±2 dB over the full 40 to 85°C operating temperature range. The HMC1013LP4E consumes only 600 mW from a single 3.3-V supply. ($1,523.80 ea/10 available now.)
