RA-30 Stepped Attenuator (30 dB)
The RA-30 consists of three high-power attenuators that can be manually switched in or out. This allows the attenuation to be increased in 6-dB steps, up to a maximum of 30 dB. It is useful in reducing the output of a gated amplifier without distorting the shape of the RF burst. The RA-30 is capable of handling pulse power in excess of 5 KW and an average power dissipation of 5 Watts. Attenuation characteristics are maintained up to about 50 MHz with an accuracy of approximately 5 percent.
