Overview
The HMC661LC4BTR, produced by Analog Devices Inc., is a SiGe monolithic, fully differential, single rank, track-and-hold (T/H) amplifier. This device is designed to provide unprecedented bandwidth and dynamic-range performance to wideband sampled signal systems. It offers precision signal sampling over an 18 GHz bandwidth, with 9-10-bit linearity from DC to beyond 5 GHz input frequency, and features ultra-clean output waveforms with minimal glitching. The HMC661LC4BTR can be clocked to 4 GS/s with minimal dynamic range loss, making it ideal for various high-speed applications.
