TBCS101-TGA

DC-coupled Low Noise Amplifier

The Tekbox TBCS101-TGA is a DC-coupled low-noise amplifier designed to boost low-level signals from DC up to tens of MHz, making it especially useful as a driver amplifier for high-power DC-coupled RF amplifiers and to enhance the output of tracking generator signals in measurement receivers. It’s ideal for use in EMC test setups and lab signal conditioning.

Features

Key capabilities and advantages

  • DC-coupled design for low–frequency and RF signal amplification.
  • Provides flat gain across its intended frequency range — excellent for consistent amplification.
  • Designed to boost the output of RF tracking generators and other weak signal sources.
  • Suitable as a driver amplifier for larger DC-coupled amplifiers in measurement chains.
  • Compact amplifier with standard BNC-female RF connectors for easy integration.
  • USB-C powered with a simple indicator LED for power status.
  • Robust and portable, suitable for test benches and EMC pre-compliance setups.
