Description
M/A-COM's PH1214-25M is a silicon bipolar NPN power transistor designed for use in L-band, 1.2 - 1.4 GHz pulsed radars such as air traffic control and long-range weather radars. Designed for common-base, class C, broadband pulsed power applications, the PH1214-25M can produce 25 watts of output power with medium pulse length (150 µS) at 10 percent duty cycle. The transistor is housed in a 2-lead, rectangular metalceramic flange package, with internal input and output impedance matching networks. In addition to L-band pulsed radars, this high performance transistor can also be used in pulsed digital communication systems.
