RF CHARACTERIZATION OF THE SEMICONDUCTOR JUNCTION IGNITER IN THE 2.75FOLDING FIN AIRCRAFT ROCKET

The design and characterization of a novel passive ignition sq stem wh ich consists of a simple two-stage radio frequency (RF) low pass filte r and a novel RF insensitive electro-explosive device is discussed [1] -[3]. Lumped parameter modeling was used to provide the frequency resp onse of the circuit. The 2.75 Folding Fin Aircraft Rocket (2.75 FFAR) was utilized as a test vehicle for field measurements which were perfo rmed as specified in MIL-STD 1385B at the Naval Surface Warfare Center in Dhalgren, VA. The configuration exhibited excellent performance ov er the entire frequency range of 1.5 MHz to 1 GHz.
