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. De-
signed for common-base, class C, broadband pulsed power
applications, the PH1214-12M can produce 12 watts of output
power with medium pulse length (150µS) at 10 percent duty
cycle. The transistor is housed in a 2-lead, rectangular metal-
ceramic flange package, with internal input and output
impedance matching networks. Diffused emitter ballast resis-
tors and gold metalization assure ruggedness and long-term
reliability.
