Calian TW127 25dB Inline RF Amplifier (Upper Band GNSS)
25dB In-Line Amplifier with Low Noise Performance
Calian TW127 25dB Inline RF Amplifier is a rugged, waterproof 25dB gain in-line amplifier designed to boost GNSS L1 signals across 1559 MHz to 1610 MHz. With low noise amplification and a high-rejection mid-section SAW filter, it enables extended cable runs without signal degradation. Powered via the antenna coax from the receiver, TW127 is ideal for commercial, industrial, and military applications requiring reliable GNSS signal enhancement in harsh environments.
