Continuously Variable Coaxial Attenuators
RLC Electronics’ Continuously Variable Coaxial Attenuators offer wide bandwidths for microwave applications where continuous adjustment of signal level is required with low insertion loss and good impedance matching. Unique mechanical packaging with a locking, non-translating shaft allow a compact assembly. The slab line construction of the transmission line and shaped, proprietary lossy material give flat response over a wide range of attenuation.
