Introduction

Coaxial video amplifiers play a crucial role in maintaining signal integrity in video transmission systems. When transporting video signals over long distances, these amplifiers ensure that the signal remains strong and clear. This article examines the function of coaxial video amplifiers, their specific parameters, and provides insight into solutions offered by Pearmain Electronics.

Function of a Coaxial Video Amplifier

A coaxial video amplifier is designed to boost video signals transmitted via coaxial cables. These amplifiers help in preventing signal degradation that can occur due to the inherent losses in long cable runs. The primary functions include:

• Signal Strengthening: Amplifies weak signals to ensure they are strong enough to be processed by receiving equipment.
• Impedance Matching: Ensures impedance matching between the cable and devices to minimize signal reflections and losses.
• Bandwidth Preservation: Maintains the integrity of high-frequency components to preserve image quality.

Specific Parameters and Numerical Analysis

Key performance parameters for coaxial video amplifiers include:

• Gain: Typically between 10 dB to 30 dB, allowing for compensating signal loss over distances up to 500 meters.
• Bandwidth: Supports frequencies from 40 MHz up to 1 GHz, suitable for various video formats.
• Noise Figure: Should be below 5 dB to prevent additional noise from degrading the signal quality.
• Impedance: Typically set at 75 ohms to match standard video equipment and cabling.
