ACCOMPLISHMENTS
- Monolithic implementation using
gallium arsenide switching devices achieved high isolation,
low loss performance
- Modular design allowed cascading
of switch matrices with little signal degradation
|
COMMERCIALIZATION
- MMIC technology offered ten
times reduction in size, weight, and power requirements over
competing technology
- A Phase III NASA Glenn contract
for $1.23M was received to develop a fully integrated 6X6
switch matrix
- A 6X6 switch matrix was delivered
to NASA Glenn Research Center, which performed as specified
- Marketing this product led to
substantial adjunct sales of space flight GaAs MMIC based
hardware
|
GOVERNMENT/SCIENCE
APPLICATIONS
- Demonstrated that for future
wideband satellites light weight, low power switch matrices
can be fabricated
- Provided a building block for
future microwave integrated circuits
