Crossed-Field
Amplifiers
 L-3
Communications Electron Devices is the world leader in Crossed-Field
Amplifier (CFA) production and development, delivering devices
from L to X-Band, with power levels from 60 kW to 5 MW peak.
L-3 CFAs are currently being produced for some of the world's
most advanced radar systems such as the Aegis AN/SPY-1 and
the Patriot Missile System.
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 light weight, 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
phase array applications.
At L-3, 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. L-3's CFA
technical staff will be there for providing the most reliable
solution.
