DESCRIPTION
The J/SST/U308 series offers superb amplification characteristics.
Of special interest is its high-frequency performance. Even at 450
MHz, this series offers high power gain at low noise.
Low-cost J series TO-226AA (TO-92) packaging supports
automated assembly with tape-and-reel options. The SST series
TO-236 (SOT-23) package provides surface-mount capabilities
and is available with tape-and-reel options. The U series
hermetically-sealed TO-206AC (TO-52) package supports full
military processing. (See Military and Packaging Information for
further details.)
For similar dual products packaged in the TO-78, see the
U430/431 data sheet.
