10W SMA 2db Attenuator coaxial Attenuator sma male to female DC-3GHz 50ohm

Construction and usage
Attenuators are usually passive devices made from simple voltage divider networks. Switching between different resistances forms adjustable stepped attenuators and continuously adjustable ones using potentiometers. For higher frequencies precisely matched low VSWR resistance networks are used.

Fixed attenuators in circuits are used to lower voltage, dissipate power, and to improve impedance matching. In measuring signals, attenuator pads or adapters are used to lower the amplitude of the signal a known amount to enable measurements, or to protect the measuring device from signal levels that might damage it. Attenuators are also used to 'match' impedance by lowering apparent SWR.

Warning:  When the input power is high than dummy provide, this is damage the dummy load.

Why use the dummy load?
A Dummy Load is a device used to simulate an electrical load during testing. In an RF System a dummy load is used to simulate an antenna. By using a dummy load instead of an actual antenna, the transceiver can be tested and configured without radiating radio waves.

The Dummy Load is selected in a way so that it has a similar impedance to the real device that will be connected to the RF System.Not using a dummy load and leaving the port open, can result in some unwanted reflections which can damage the RF System. Also, using a real antenna in the testing phase can result in some unwanted transmission in the lab which will interfere with other devices and technologies being tested.
