RA-32 Stepped Attenuator (40 dB)
The RA-32 consists of three high-power attenuators that can be manually switched in or out. This allows the attenuation to be increased in 8-dB steps, up to a maximum of 40 dB. It is useful in reducing the output of a gated amplifier without distorting the shape of the RF burst. The RA-32 is capable of handling pulse power in excess of 5 KW and an average power dissipation of a 5 Watts. Attenuation characteristics are maintained up to about 50 MHz with an accuracy of approximately 5 percent.
