Sotca Inc. designs and manufactures a wide range of high-performance cost RF & Microwave products in L, S, C, X, Ku frequency bands, using the most advanced surface mount(SMT) and MIC hybrid technology. All designs are based on the best available HEMT, GaAs FET and LDMOS semiconductors. Capitalizing on top-notch engineering and more then 50 years of experience in the field allows us to develop high-performing, yet simple, economically priced components and subsystems with a high degree of reliability.

Synthesized Agile Frequency Converters

Sotca's new generation High Performance and Low-Cost synthesized frequency converters are designed for use in advanced satellite communication systems.
They feature high amplitude linearity, low phase noise, low intermodulation and group delay distortion.

An extensive set of monitoring and control functions supports local and remote RS485/RS422/RS232 and Ethernet unit control. The modular design allows to configure them as single separate upconverters or downconverters, or as a combination up/downconverter, packed into 1.75" (1U) Rack.
