- Improves sensitivity for weak RF signals — perfect for lab and test measurements.
- Can act as pre-amplifier for measurement receivers like the TBMR-110M.
- Suitable for general low-frequency RF applications where conventional amplifiers may have higher noise.
- Pin-diode input protection helps safeguard against input overload.
- Compact housing with BNC-female RF connectors.
TBLNA-110M-50
DC-coupled Low Noise Amplifier
The Tekbox TBLNA-110M-50 is a DC-coupled low noise amplifier (LNA) that provides high gain for very low-level RF signals from DC up to 110 MHz. It is ideal as a pre-amplifier for measurement receivers, spectrum analyzers, and general-purpose RF applications where superb low-noise performance is needed.
