Product Specifications
Crossed-Field Amplifiers are non-linear saturated amplifiers characterized by high efficiency, moderate gain and bandwidth, and low noise performance. They are also relatively small and lightweight, operate at low voltages yet are capable of extremely high peak powers. For this reason, they are attractive choices for mobile, shipboard and airborne radar applications. Excellent phase coherency, control and linearity make the CFA an excellent choice for phased-array applications.
At L3Harris, the latest technology serves as a starting point for continuous innovation. We employ the most experienced CFA engineers and physicists, and strive to produce better products through advanced material, design and technique development. In the cases where a customer requires a device with a tailored specification, scaling of an existing CFA to meet the requirements can be accomplished. L3Harris' CFA technical staff will be there for providing the most reliable solution.
