want to patch together and simulate various scenarios, configurations and cable lengths." To support these teams, Norton
said, "We developed our BS1553F automated patching unit to
automate this patching under software or front-panel control."
Alderson said that to help control budgets, USC manufacture
modular hardware where customers can begin with a smaller
configuration and expand as more funding is acquired, an approach taken with the BS1553F, which can be configured from
8x8 to 64x64 in increments of eight ports in symmetrical or
asymmetrical configurations."
As for applications, "We serve nearly all Major Range and Test
Facility Bases (MRTFB) across the nation as well as satellite
ground stations, Amy, Navy and Airforce Research Laboratories,"
Alderson said. "Also, we serve a large majority of defense contractors and government agencies including NOAA, NASA and
the newly formed US Space Force."
Menlo Micro offers a line of MEMS switches, and the company's switch technology has been designed into a new line RF
subsystem products, such as a miniaturized UHF tunable filter
targeting milcom manpack and handheld radio systems, a phase
shifter, and an RF switch matrix, with a roadmap for additional
subsystems, according to Jonathan Leitner, senior product marketing engineer."

MIL-STD-461 and MIL-STD-464 testing
AR RF/Microwave Instrumentation focuses on topics such as
EMC testing. The company is seeing more effort being focused
on MIL-STD-464, which covers entire systems rather than system component testing, according to Dean Landers, applications engineer, adding that the
company's products are used
worldwide for MIL-STD-461
and MIL-STD-464 testing.
"As always, the biggest
challenge facing radiated susceptibility testing is the 100MHz to 200-MHz frequency
range, where antennas often
have negative gain," Landers
said. "This can result in severe impedance mismatches
which lead to low delivered
power and high ref lected
power. Fortunately, our amplifiers can withstand the
results of these heavy misAR RF/Microwave Instrumentation custom system. Courtesy AR RF/
matches with no damage to
Microwave Instrumentation.
the amplifier output."
Landers said, "We can also incorporate a customer's existing equipment into our system for seamless integration and
operation."
Spira Manufacturing offers gaskets and filters for DoD weapon systems in simulated Faraday cages to ensure the systems
operate properly in their designated environment without experiencing or adding EMI, according to George Kunkel, CEO
