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.
