GENERAL DESCRIPTION

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 intelli-

gence (ELINT), and automated test equipment (ATE).
