DAT & AT SERIES
Electronic control. Flexible attenuation.
Taylor Microwave solid-state attenuators provide electronically controlled signal-level adjustment. DAT Series units combine switched diode-resistor networks with T-pad attenuation elements to select discrete attenuation values.

Attenuator Circuit
Features & Configuration
DAT Series
Discrete attenuation is selected by switching individual diode-resistor sections. Bit count and attenuation values can be configured for the application.
AT Series
Electronically controlled attenuation uses diode-resistor networks to maintain low VSWR across attenuation settings. Contact us for specifications for your application.
