BroadWave Technologies has developed an electromechanical 75 Ω Programmable Attenuator with an external TTL control board and BNC female connectors. Model 674-041-063 offers a dynamic range of 63 dB in 1 dB steps over a frequency range of DC – 1000 MHz. Attenuation accuracy is +/- 0.5 dB or 2% of programmed, 1.50:1 maximum VSWR and 3.0 dB insertion loss. The switching speed is 10 milliseconds and TTL control is via a 10-pin connector with a latch. Other impedance and connector options are also available. Please contact us with your unique requirement for the appropriate model number.
