Description
The U440/441 are matched pairs of JFETs mounted in a
single TO-71 package. This two-chip design reduces
parasitics and gives better performance at very high
frequencies while ensuring extremely tight matching. These
devices are an excellent choice for use as wideband
differential amplifiers in demanding test and measurement
applications.
The hermetically-sealed TO-71 package is available with
full military screening per MIL-S-19500 (see Military
Information).
For similar products in SO-8 packaging see the
SST440/SST441 data sheet. For low-noise opions, see the
SST/U401 series data sheet. For low-leakage alternatives,
see the U421/423 data sheet.
