DESCRIPTION
Celeritek has developed linear upconverter assemblies
for point-to-point radio applications for both the United States
and European frequency bands. The upconverters operates at
21.2 to 22.6 GHz or 22.4 to 23.6 GHz with complementary
down converters.
EXPERIENCE AND CAPABILITIES
Celeritek is one of the major suppliers of commercial
communication microwave equipment to OEM suppliers. The
company’s in-house GaAs FET and MMIC capabilities, along
with extensive amplifier products, provide the basis for
Celeritek to offer high-performance products at competitive
prices in the commercial market. Also, the company uses a
combination of thin-film and softboard techniques to reduce
manufacturing costs and maintain high reliability.
Celeritek has a separate dedicated production line
and engineering team for communications products. This staff
in highly experienced in the development and production of
high-reliability, low-cost commercial products.
