Overview

  • 18 GHz Input bandwidth (1 VP-P Full Scale)
  • 68 dB SFDR (4 GHz/0.5 VP-P Input, CLK = 1 GS/s)
  • 57 dB SFDR (4 GHz/1 VP-P Input, CLK = 1 GS/s)
  • Ultra-clean Output Waveforms, Minimal Glitching
  • 4 GS/s Maximum Sampling Rate
  • >60 dB Hold Mode Feedthrough Rejection
  • 1.05 mV RMS Hold Mode Output Noise
  • Single/Dual Rank Eval Boards Available
  • RoHS Compliant 4×4 mm SMT Package

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.
