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 available 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: 0.25 watt |
Shaft: Screwdriver adjust with optional shaft lock. Attenuation increases with counter clockwise rotation. Approximately 3.5 turns for maximum attenuation. |
To designate the attenuator 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
