The 50P-2057 from JFW Industries is a Solid-State Programmable Attenuator that operates from 200 to 6000 MHz. This USB-controlled device has eight individually controlled attenuation steps: 0.5, 1, 2, 4, 8, 16 and 32 dB to cover a total attenuation range from 0 to 95.5 dB in 0.5 dB steps. It has an insertion loss of less than 8 dB, VSWR of under 1.8:1, and a switching speed of up to 4 microseconds. The unit operates bi-directionally and can handle up to 27 dBm of power at the input port. It can be controlled using a software solution provided by JFW Industries. This 50-ohm attenuator requires a 5 V DC supply and is available in a module with SMA connectors.
