1821TH
Overview
The 1821TH track-and-hold amplifier is designed for high-precision sampling of wideband signals with multi-GHz frequency content. The masterslave architecture integrates two track-and-hold circuits, a 50-ohm differential output buffer, and clock mode selection logic.
- Supports 2 GS/s sampling rate
- 18 GHz input bandwidth (small-signal)
- 15 GHz input bandwidth (0.5 Vpp)
- 12 GHz input bandwidth (1 Vpp)
- THD < -60 dB (1 GHz 1 Vpp input)
- THD < -35 dB (10 GHz 0.5 Vpp input)
- Fast rise time: < 25 ps (10 - 90%)
- Ultra low aperture jitter: < 50 fs
- 0 dB Gain with up to 1 Vpp out
