News: TS-5000 SMA Termination

Tesoel, founded in 1973, has been producing high quality RF-and Microwave Coaxial Switches ever since. Full attention is devoted to any specific switch requirement. Tesoel offers a wide range of electromechanical switches for commercial and military applications. The basic microwave performance is similar for all types, the difference lies in the environmental specifications. SMA SPDT-switches


Commercial grade switches
The SMA-switches in this category are characterised by very low actuator current consumption and small dimensions. This makes them ideal for mobile and battery operation. The RF-circuit is SPDT to SP6T and Transfer. The operating mode is latching or fail-safe.
The N-connector models are capable of handling high average and peak powers. With special dielectric material the power handling capability is as high as 600W at 1 GHz.

Military grade switches, TS800-series
These switches have fully balanced actuators which makes them capable of withstanding severe vibration and shock. They are available in SPDT and Transfer configurations and the operating modes are latching or fail safe.

Multipole SMA-switches
Special Coaxial Connectors
In addition to coaxial switches Tesoel manufactures coaxial connectors with non standard external dimensions. The modern machineshop with NC-machines gives high flexibility and quick reaction time, essential in today's fast moving market.
