DC to 18 GHz, Ultra Wideband, Dual Rank, 4 GSPS Track-and-Hold Amplifier

The HMC1061LC5 is a silicon germanium (SiGe), monolithic, fully differential, dual rank, track-and-hold amplifier that provides unprecedented bandwidth and dynamic range performance to wideband sampled signal systems. The track-and-hold amplifier offers precision signal sampling over an 18 GHz bandwidth, with 9-bit to 10-bit linearity from dc to beyond 5 GHz input frequency, 1.45 mV noise, and <70 fs random aperture jitter.

The HMC1061LC5 can be clocked to 4 GSPS with minimal dynamic range loss. The track-and-hold amplifier can be used to expand the bandwidth and/or high frequency linearity of high speed analog to digital conversion and signal acquisition systems. Wideband data acquisition systems with multi GHz required bandwidth for a variety of applications, such as software defined radio, radar systems, electronic warfare (EW), electronic intelligence (ELINT), and automated test equipment (ATE).
