Description

M/A-COM’s PH2729-150M is a silicon bipolar NPN transistor

specifically designed for use in high efficiency, common base,

Class C microwave power amplifiers. It is ideally suited for S-

Band radar and pulsed power applications where the highest

gain and saturated power are required.

The flanged ceramic

package provides for excellent thermal and hermetic properties,

which when combined with M/A-COM’s mature transistor fab-

rication technology results in the highest reliability available.
