Test Service

OTA chamber and testing equipment

Cirocomm antenna labs consists of ETS chamber, Satimo instrument, other testing equipment and experienced RF engineers. We not only provide antenna and filter design service, but also conducting test of antennas and filters to ensure that the final performance does meet your need.

What are Cirocomm’s missions?
Our Antenna Test Facilities focus on assessing antenna performance, an essential element of satellite systems. These facilities support testing across the entire spectrum of antenna development, from characterizing the properties of potential materials for antennas— including measurement of their RF absorption, reflectivity and dielectric properties— to assessing the performance of antenna subsystems, up to full-scale complex radiating systems comprising of fully-integrated satellites incorporating multiple antennas onboard.

Cirocomm’s test equipment consists of a fully anechoic chamber for antenna testing, measurement, and qualification. This chamber is used during the antenna design process to ensure proper operating performance and record antenna patterns and compile test data for customer.
