Description
M/A-’s PH1214-220M 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 weather radars. Designed for mon-base, class C, broadband pulsed power applications, the PH1214-220M can produce 220 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.
