Description
M/A-COM’s PH1214-40M is a silicon bipolar NPN power
transistor intended for use in L-band, 1.2 - 1.4 GHz pulsed
radars such as air traffic control and long-range weath er radars.
Designed for common-base, class C, broadband pulsed power
applications, the PH1214-40M can produce 40 watts of output
power with medium pulse-length (150µS) 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 assures ruggedness and long-term
reliability.
