TekBox TBMDA3B Modulated Wideband Power Amplifier

Overview

The TBMDA3B is a low-cost modulated wideband power amplifier designed to provide an RF power source for pre-compliance immunity testing of electronic building blocks and products. Operating from 10 MHz to 1 GHz, it delivers up to 8W saturated output power when driven with an input power of less than 0 dBm. The amplifier is ideal for driving TekBox near field probes or generating strong electric fields for radiated immunity testing in TEM cells.
