V1.1TBMDA4B布T巨K旦O×DIGITAL SOLUTIONSModulated Wideband Power Amplifier1 IntroductionThe TBMDA4B modulated wideband power amplifier is designed in order to create an inexpensive signal sourcefor immunity testing of electronic building blocks and products.It is designed to be driven by the trackinggenerator output of spectrum analyzers.With an input power range of-20 dBm...-10 dBm,it can boost theoutput power of a tracking generator up to 5W.With a frequency range from 100 kHz to 75 MHz,it is an idealcomplement to the TBMDA3,which covers 10 MHz to 1 GHz.The TBMDA4B is ideal to drive Tekbox near fieldprobes in order to find the sensitive spot of an electronic circuit or to create electric fields up to 550V/m whendriving the Tekbox TEM Cell TBTCO,300V/m when driving the TBTC1,150V/m when driving the TBTC2 or100V/m when driving the TBTC3.Test signals for immunity testing can be CW,AM or PM modulated.Consequently,the TBMDA4B provides built in modulation capability to generate 1 kHz AM or PM signals.In PMmode,the TBMDA4B can also generate a 217 Hz Signal with 12.5%duty cycle in order to simulate mobilephone TDMA noise.TEKBOXPicture 1-TBMDA4B modulated wideband driver amp lifier.front viewPicture 2-TBMDA4B modulated wideband driver amplifier,rear view1
