General Description
The HMC661LC4B is a SiGe monolithic, fully
differential, single rank, track-and-hold (T/H) that
provides unprecedented bandwidth and dynamic-range
performance to wideband sampled signal systems.
The T/H offers precision signal sampling over 18 GHz
bandwidth, with 9 - 10-bit linearity from DC to beyond
5 GHz input frequency, 1.05 mV noise, and <70 fs
random aperture jitter. The device can be clocked to 4
GS/s with minimal dynamic range loss. The T/H can be
used to expand the bandwidth and/or high-frequency
linearity of high-speed A/D conversion and signal
acquisition systems.
Electrical Specifications TA = +25 °C, See Test Conditions on following page herein.
