SMW L-Band Amplifier AGC Line, 22 kHz and 10 MHz bypass
The AGC Line Amplifier L-Band by Swedish Microwave is engineered to provide a consistent output level from a Low Noise Block (LNB) in satellite communication systems. Its Automatic Gain Control (AGC) feature dynamically adjusts gain from 0 to 30 dB, ensuring stable signal levels despite varying input conditions.
Key Features:
- Automatic Gain Control (AGC): Adjusts gain between 0 to 30 dB to maintain a constant output.
- High Linearity: Exhibits high Output Third-Order Intercept Point (IP3), allowing installation close to the LNB without significant distortion.
- Outdoor Durability: Rated IP67 for protection against dust and water ingress, suitable for various environmental conditions.
- Connector Options: Available with F-type, N-type, or SMA connectors to accommodate different system requirements.
- DC Bypass Standard: Facilitates power supply to the LNB through the amplifier.
- Optional Separate DC Input: Offers flexibility in power sourcing.
