NuWaves Engineering Partners with NASA

February 22, 2012 Press Release
Middletown, Ohio, February 22nd, 2012 – NuWaves Engineering, an
international Radio Frequency (RF) solutions company, has been awarded
a contract to design and manufacture prototype High Efficiency Switching
Power amplifiers for Earth Radar Observation Systems (HESPEROS) by NASA,
as part of the government agency’s efforts to pursue smaller and more
affordable spacecraft.
 To
meet the multiple mission needs with limited resources of NASA’s Earth
Science Division, RF components will need to be smaller and more power
efficient. The reduction of size, weight, power, and cost (SWaP-C) of
RF components required for a particular mission area allows the instrumentation
package to be made more compact. HESPEROS applies several innovative
techniques to increase the efficiency and operational bandwidth of RF
power amplifiers (PAs) targeted for radar applications. The design also
incorporates fast turn-on, and turn-off circuits to achieve switching
times of less than one microsecond (μs). The benefit of such amplifiers
in radar applications is that they can be switched off during the receive
period to prevent self-generated noise from corrupting the received
signal. Also, high-power transmit and receive (T/R) switches at the
antenna feed can be eliminated.
In addition, the wideband PA
enables the design of a multi-band radar, reducing the number of components
needed for operation in the P, L, and X bands. A high-efficiency PA
is also key to reducing battery size and cooling requirements in spaceborne
applications. Ultimately, other applications for this highly efficient
PA for radar based applications include other primary mission critical
communication functions like telemetry, telecommand, land and sea radar
systems, navigation and guidance control, flight termination, craft-to-craft
communications, and TDRSS reply and relay.
“We’re excited to
be working with NASA to help drive down the size, weight, and power
consumption required for wideband power amplifiers used for radar,”
said Jeff Wells, President and CEO of NuWaves Engineering. “These innovations
will not only benefit NASA in its pursuit of next-generation spacecraft
technologies, but also other government and commercial customers with
similar operational requirements.”
