Description
M/A-COM’s PH1214-80M 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 PH1214-80M can produce 80 watts of output
power with medium pulse length (150 µS) 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. Dissued emitter ballast resistors
and gold metalization assure ruggedness and long-term reliabil-
ity. In addition to L-band pulsed radars, this high performance
power transistor can also be used in pulsed digital communica-
tions systems.
