TBHDR1 High Dynamic Range Amplifier

Overview

The TBHDR1 is a high dynamic range amplifier with a frequency range from 30kHz to 1.5GHz. Its gain is characterized up to 6GHz.
The TBHDR1 has a high IP3 and a low noise figure which makes it an ideal alternative pre-amplifier for spectrum analyzers and receivers in EMC test applications. Due to its low noise figure, high IP3 and gain down to the kHz range it also performs very well as amplifier for active loop antennas.
