Description
The TBLNA-110M-50 is a DC-coupled amplifier with a gain of 40 dB in the frequency range DC–110 MHz.
Applications:
- External pre-amplifier for the measurement receiver TBMR-110M
- Pre-amplifier for amplifying low-level input signals to spectrum analyzers
- General-purpose LNA for low and very low frequency applications, where conventional LNAs sometimes suffer from an increase in noise figure.
