Description
Model 50P-2072 is a 50 Ohm solid-state programmable attenuator with attenuation range 0 to 31dB by 1dB steps. It operates 100 MHz to 40 GHz and is rated for +20 dBm of RF input power (0.1 dB compression at +25 dBm). This step attenuator is available with 2.9mm female coaxial RF connectors. The attenuator has five individually controlled steps: 1dB, 2dB, 4dB, 8dB and 16dB.
TTL Controlled with Inverted Logic
Each of the attenuation steps has a corresponding TTL control line. There are five TTL control lines for this model. See the outline drawing for the control pinout. TTL low will turn on an attenuation step. TTL high will turn off an attenuation step. Use multiple control lines simultaneously to set combinational attenuation values. To activate the 7dB setting, the 1dB/2dB/4dB control lines must all be TTL low. To activate the 18dB setting, the 2dB/16dB control lines must be TTL low. To set the attenuator to the insertion loss state (i.e. 0dB setting), all control lines must be set to TTL high. To set the attenuator to its maximum dB setting (31dB), all control lines must be set to TTL low.
