Variable/step attenuator can be used to adjust the power signal level continuously or by step within certain frequency range, they can also to adjust the test system's power as inset attenuator. It is small with high accuracy and high stability etc.
Kete Microwave offers a series of step/variable attenuators from 2W to 30W with N, SMA or BNC. These parts can work at operating temperature range from -20℃~+85℃. If there have questions or requests, please contact with Kete Microwave.
