The ETL Systems ATT20L1P-4212 is a fixed 20 dB L-band attenuator designed to reduce signal strength within the 850–2150 MHz frequency range. This model is particularly suited for applications where DC power needs to pass through the attenuator, but 10 MHz reference signals should be blocked.
Available with RF connector options: 50 Ω SMA, 50 Ω N-type, 50 Ω BNC, 75 Ω BNC and 75 Ω F-type.
Key Features:
- DC Pass
- Tubular Housing
- Available with 3, 6, 10 or 20dB attenuation
