The TekBox TBMDA3 and TBMDA4 Modulated Wideband Power Amplifiers have been specifically designed to provide an economical signal source for immunity testing of electronic circuits and products. While these amplifiers are intended to increase the output of a spectrum analyzer’s tracking generator, they are also useful as general-purpose wideband RF signal amplifiers. The TBMDA3 and TBMDA4 are candidates for driving near-field probes to find sensitive spots on electronic circuits, or for creating strong electric fields of up to 550V/m when driving TEM Cells. With an input power range of -5 dBm to 0 dBm, they can boost signal power up to 5 W. The TBMDA3 has a frequency range from 10 MHz to 1 GHz, while the similar TBMDA4 covers a range of 100 kHz to 50 MHz.
Test signals for immunity testing can be continuous wave or AM or PM modulated by the TBMDA3 and TBMDA4, which both provide built-in modulation capabilities to generate 1 kHz AM or PM signals. In PM mode, they can also generate a 217 Hz signal with 12.5% duty cycle for simulating mobile phone TDMA noise.
