Description
Model 50P-2070 is a 50 Ohm solid-state programmable attenuator with attenuation range 0 to 63.75dB by 0.25dB steps. It operates 30-3000 MHz and is rated for +27 dBm of RF input power. This step attenuator is available with SMA female coaxial RF connectors. The attenuator has eight individually controlled steps: 0.25dB, 0.5dB, 1dB, 2dB, 4dB, 8dB, 16dB and 32dB.
TTL Controlled
Each of the attenuation steps has a corresponding TTL control line. There are eight TTL control lines for this model. See the outline drawing for the control pinout. TTL high will turn on an attenuation step. TTL low will turn off an attenuation step. Use multiple control lines simultaneously to set combinational attenuation values. To activate the 7.5dB setting, the 0.5dB/1dB/2dB/4dB control lines must all be TTL high. To activate the 18dB setting, the 2dB/16dB control lines must be TTL high. To set the attenuator to the insertion loss state (i.e. 0dB setting), all control lines must be set to TTL low.
