ETL Systems RF Amplifiers – Fixed Gain, Variable Gain & AGC

ETL Systems RF Amplifiers – Fixed Gain, Variable Gain & AGC

ETL Systems offers RF amplifiers for signal amplification and level adjustment across satellite communications and RF distribution systems. The wider portfolio spans frequency ranges from DC to 24 GHz, with individual models designed for specific bands and applications.

Available amplifier types include fixed gain (GAB), variable gain (VGA), automatic gain control (AGC), and SMART VGA. The attached overview lists fixed and variable gain models operating from 850–2150 MHz, plus AGC models covering 50–2500 MHz.

Connector options include SMA, N-type, BNC, and F-type, with 50Ω or 75Ω configurations depending on the model. Rectangular and compact tubular housings are available across the range; tubular designs use in-line powering.

Select the required amplifier by frequency range, gain requirements, input and output signal levels, connector type, impedance, and power supply.
