Designed for mon-base, class C, broadband pulsed power applications, the PH1214-110M can produce 110 watts of output power with medium pulse length (150µS) 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. Diffused emitter ballast resistors and gold metalization assure ruggedness and long-term reliability. Notes: (unless otherwise specified) 1.
