| Radar Pulsed Power Transistor 25 Watts, 1.20-1.40 GHz, 150s Pulse, 10% Duty PH1214-25M PH1214-25M Radar Pulsed Power Transistor - 25 Watts, 1.20-1.40 GHz, 150S Pulse, 10% Duty Features * * * * * * * * NPN Silicon Microwave Power Transistor Common Base Configuration Broadband Class C Operation High Efficiency Interdigitated Geometry Diffused Emitter Ballasting Resistors Gold Metalization System Internal Input and Output Impedance Matching Hermetic Metal/Ceramic Package Outline Drawing 1 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 S) 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. Notes: (unless otherwise specified) 1.
