TBLNA-110M-HZ - DC-coupled Impedance Converter
The TBLNA-110M-HZ is a DC-coupled Impedance Converter from 1 MΩ to 50 Ohm with a flat response in the frequency range from DC to 110MHz and a 3 dB bandwidth from DC to 500 MHz. One of the impedance converter’s two separate outputs has a gain of 0 dB, while the other has a gain of 20 dB. When the TBLNA110M-HZ is used with a 1:10 oscilloscope probe, this corresponds to a gain of -20 dB or 0 dB.
Application
In-circuit measurements in 50 Ohm systems, using standard oscilloscope probes.
High impedance frontend for spectrum analyzers and other RF-equipment with 50 Ohm inputs.
