Recent advances in millimeter-wave solid-state transmitters
Abstract
Millimeter-wave weapon systems have operational capability under adverse weather conditions, while maintaining reasonable resolution for precision strike. Unfortunately, atmospheric attenuation increases with increasing operational frequency. Power requirements for millimeter-wave systems are, therefore, considerably higher than for corresponding microwave systems. Solid state power transmitters with power output levels in the tens of watts, small size, light weight, and potential low cost, are ideal for applications where the range is between 3 and 10 km. The applications specifically include the terminal missile guidance, fuses, sensors, and smart projectiles. The two most commonly used solid-state devices in millimeter-wave systems are the IMPATT and Gunn diodes. Silicon IMPATTs have demonstrated far superior frequency performance and reliability than GaAs devices. Attention is given to combiners, and aspects of system application.
