Description
Model 50P-1683 is a 50 Ohm relay programmable attenuator with attenuation range 0 to 70dB by 10dB steps. It operates DC-2500 MHz and is rated for 0.5 Watts of RF input power. This step attenuator is available with BNC, N, SMA or TNC coaxial RF connectors. The attenuator has four individually controlled steps: 10dB, 20dB, 20dB and 20dB.
+12Vdc Controlled
Each of the attenuation steps has a corresponding solder feedthru where the control Voltage is applied. Applying +12Vdc to a solder feedthru will turn on the attenuation for that step. The internal relays are failsafe to their thru path setting (i.e. failsafe to 0dB setting). An open circuit (or Ground) on a solder feedthru will turn off the attenuation for that step. Activate multiple steps simultaneously to set combinational attenuation values. For a 30dB setting, the 10dB/20dB control lines must active. For the 60dB setting, the 20dB/20dB/20dB control lines must be active. To set the attenuator to the insertion loss state (i.e. 0dB setting), all control lines must off (i.e. Ground or Open Circuit).
