Trilithic's
RSA series rotary attenuators are recognized worldwide as the standard for
durable, precise signal level control. The series is divided into both 50 and 75
ohm units with attenuation as high as 110 dB dynamic range (in 10 dB steps), or
as low as 1 dB range ( in 0.1 dB steps). A firm, snap action detent locks in the
desired attenuation as indicated on the supplied control knob. Low VSWR and
insertion loss is assured throughout the range of each unit with tightly
controlled pad values and machining tolerances.
Rotary Step Attenuator Features:
- Wide Frequency Range
- High Accuracy Rate
- Low VSWR
- Price Competitive
- Flexible Design Configurations
Trilithic's new state-of-the-art rotary step attenuators are designed for precision control of signal levels in the DC to 3.0 GHz range and are offered in a wide choice of values and increments. This new design allows for greater automation of assembly and unprecedented low cost. Please contact the factory for your custom attenuator needs.
