25 W Coaxial Fixed Attenuators DC-26.5 GHz Connector SMA
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.
SMA25 series coaxial fixed attenuator average power 25W, 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.
