DC To 1000 MHz Continuously
Variable Coaxial Attenuators
RLC Electronics’ Low Frequency Continuously Variable Coaxial
Attenuators offer wide bandwidths for applications where
continuous adjustment of signal level is required with low
insertion loss and good impedance matching. Units are avail-
able for 50 ohm and 75 ohm applications with three different
mounting configurations and four connector options. Both
models LAV-V and LAV-C are designed for optimum VSWR and
flatness over the respective bands. The LAV-C is specifically for
the cellular frequency range.

Impedance:
50 ohms, 75 ohms
Power Rating:
1 watt
Connectors:
Type N, TNC, BNC, SMA Female
Shaft:
Screwdriver adjust with optional shaft lock. Attenuation
increases with counter clockwise rotation. Approximately 3.5
turns for maximum attenuation.
To designate the switch desired use:
(1) Blank, V, C, for model/frequency range
(2) 50, 75 for impedance
(3) N, T (TNC), B (BNC), R (SMA) for connectors
(4) L for locking shaft, LP for locking shaft with panel mount
Example: LAV-50-R-L is a DC-1000 MHz, 50 ohm attenuator with SMA connectors and a locking shaft
