50 ohm solid-state programmable attenuator (TTL)

A programmable attenuator is a variable attenuator with a specific dB step size and total attenuation. All models in this table adopt solid-state design with an impedance of 50 ohms. The attenuation step is controlled through parallel TTL control lines. JFW has been designing, manufacturing, and delivering programmable attenuators for over 25 years.

Solid state design

These attenuator models all adopt solid-state design, allowing for speed switching within microseconds. These solid-state step attenuators have no moving parts and are very suitable for automated RF testing. The attenuator has a typical MTBF of 250000 hours and excellent attenuation repeatability.

TTL control

The models listed in the table have parallel TTL lines for attenuator control lines. Each attenuation step has a TTL line. Activate multiple dB steps simultaneously to set the combined attenuation value. Example: To achieve a total attenuation of 7dB, please activate the steps of 1dB/2dB/4dB simultaneously.
