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 SBand radar and pulsed power applications where the highest
gain and saturated power are required. The flanged ceramic
package provides for excellent thermal and hermetic prop erties,
which when combined with M/A-COM’s mature transistor fabrication technology results in the highest reliability available.
