TBMDA7

Modulated Wideband Driver Amplifier

The Tekbox TBMDA7 is a modulated wideband driver amplifier that provides an affordable RF signal source for immunity testing of electronic building blocks and products. It is designed to be driven by the tracking generator output of a spectrum analyzer, making it ideal for boosting low-power signals to levels usable for EMC tests, near-field probing, and TEM cell field generation.
