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.
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.)
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
For similar dual products packaged in the TO-78, see the
U430/431 data sheet.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
