The SSA series of solid state attenuators from dBm are 7-bit Digital Attenuators that operate from 20 MHz to 3 GHz. These attenuators have an attenuation range from 0 to 95 dB with a resolution of 1 dB. They have an insertion loss of under 7.5 dB and a fast switching speed of less than 16 us. The attenuators are available in a module that measures 3.2 x 1.4 x 0.75 inches with SMA female connectors and are ideal for automatic test stations, multi-channel simulators and inter-op testing applications.
These solid state attenuators can also be configured in groups of up to 16. An addressable 8 bit parallel driver card provides a simple control interface. The interface is double buffered, so attenuation channels can be set individually, or all changed simultaneously.
