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.
