50 Ohm Solid-State Programmable Attenuators (TTL)

JFW’s online 50 Ohm solid-state programmable attenuator models with TTL control are listed in the table below.  JFW has been designing, manufacturing, and delivering programmable attenuators for over 25 years.

Solid-State Design
These attenuator models all have a solid-state design which allows for switching speeds in the microseconds.  With no moving parts, these solid-state step attenuators are perfect for automated RF testing.  The attenuators have typical MTBF of 250,000 hours and excellent attenuation repeatability.

TTL Control
The models listed in the table have parallel TTL lines for the attenuator control lines.  There is a TTL line for each attenuation step.  Activate multiple dB steps simultaneously to set combination attenuation values.  Example: to achieve 7dB of total attenuation activate the 1dB/2dB/4dB steps simultaneously.
