25 W Coaxial Fixed Attenuators DC-18 GHz Connector N,SMA,TNC
Description
The coaxial fixed attenuator is suitable for any need to reduce the power level or circuit matching, can quantitatively absorb the energy in the transmission line, extend the power range, control the power level, and can be configured with a small power meter, comprehensive tester or spectrum analyzer to accurately measure the power or spectrum of various RF microwave transmitters.
DTS series coaxial fixed attenuator average power 10W-10KW, frequency range DC-26.5GHz. It has the following characteristics: wide working frequency band, low standing wave coefficient, flat attenuation value, strong anti-pulse and anti-burn ability.
