Tekbox TBLNA Amplifier Series
Tekbox TBLNA Amplifier Series
Tekbox TBLNA-110M-50 DC-coupled Low Noise Amplifier
The Tekbox TBLNA-110M-50 is a DC-coupled amplifier with a gain of 40 dB in the frequency range DC to 110 MHz. Application: External pre-amplifier for 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.
Tekbox TBLNA-9K30 Loop Antenna Pre-Amplifier
The Tekbox TBLNA-9K30 is a pre-amplifier for the TBMA6-P, expanding the dynamic range of the passive loop antenna. The pre-amplifier is designed for the TBMA6-P, but it can be used together with any passive loop antenna for the frequency range 9 kHz to 30 MHz. The pre-amplifier is equipped with a charger for 12 pieces standard AA NiMh batteries. A ¼" thread at the bottom of the TBLAA1 permits connectivity to standard tripods.
