Description
M/A-COM鈥檚 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鈥檚 mature transistor fab-
rication technology results in the highest reliability available.
