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 options, see the

SST/U401 series data sheet. For low-leakage alternatives,

see the U421/423 data sheet.
