Develop a high-powered Radio Frequency (RF) linear power amplifier that enables
efficient, linear operation with multiple simultaneous signals across a wide
instantaneous bandwidth capable of operating in an active antenna array.
Current Navy directional, tactical communication networks operate in a one beam
at a time fashion with each message exchange assigned separate time slots. This
limits network performance and spectral usage. The next generation of
communication networks will use multiple simultaneous beams to leverage the
spatial dimension in order to establish multiple communication links
simultaneously in different directions. To achieve the major networking
advantages of multi-beam operation (discussed below) enabled by digital array
communications technology, power amplifiers will need to be developed that do
not generate unacceptably high levels of interfering nonlinear effects when
multiple communications signals are transmitted through them simultaneously.
Current state-of-the-art amplifier designs are challenged to achieve acceptable
levels of linearity performance without significant reductions in RF power,
bandwidth, and power-added efficiency. Due to the reduced link ranges and
allocated bandwidths of commercial communications, there is little investment
to meet the metrics required for Navy operation.
Define and develop a concept for a high-efficiency wideband linear power
amplifier. Demonstrate the concept can feasibly meet the Navy requirements as
provided in the Description. Establish feasibility by a combination of initial
analysis and modeling and if possible, through demonstration on existing
hardware. The Phase I Option, if exercised, will include the initial design
specifications and capabilities description to build a prototype in Phase II.
Develop a Phase II plan that includes prototype testing, evaluation, and
Develop and deliver a prototype power amplifier that demonstrates the
performance parameters outlined in the Description. Validate the prototype
through comparison of model predictions to measured performance.
DUAL USE APPLICATIONS: Support the Navy in transitioning the technology to Navy
use. Further refine the prototype for evaluation to determine its effectiveness
and reliability in an operationally relevant environment. Support the Navy in
the system integration and qualification testing for the technology through
platform integration and test events to transition the technology into PEO IWS
6 applications for simultaneous communications links to improve and expand
tactical network functionality.
