1000 W Peak, 960-1215 MHz, 50 V Airfast® RF Power LDMOS Transistors

AFV121KH
These RF power transistors, AFV121KH, AFV121KHS and AFV121KGS, are designed for pulse applications operating at frequencies from 960 to 1215 MHz, such as distance measuring equipment (DME), secondary radars and high power transponders for air traffic control. These devices are suitable for use in pulse applications with large duty cycles and long pulses, including Mode S ELM.
