Description
M/A-COM’s PH1214-12M is a silicon bipolar NPN power transistor intended for use in L-band 1.2 - 1.4 GHz pulsed radar's such as air traffic control and long-range weather radars. De­signed for common-base, class C, broadband pulsed power applications, the PH1214-12M can produce 12 watts of output power with medium pulse length (150µ S) at 10 percent duty cycle. The transistor is hous ed in a 2-lead, rectangular metal­ceramic flange package, with internal input and output impedance matching networks. Diffused emitter ballast resis­tors and gold metalization assure ruggedness and long-term reliability.
