V1.3TBMDA3B布T巨K旦O×DIGITAL SOLUTIONSModulated Wideband Power Amplifier1 IntroductionThe TBMDA3B,10MHz-1 GHz modulated wideband power amplifier is designed to provide a low-cost RFpower source for pre-compliance immunity testing of electronic building blocks and products.Driven with aninput power of less than 0 dBm,it can deliver a saturated output power of up to 8 W.The TBMDA3 is ideal todrive Tekbox near field probes in order to find the sensitive spot of electronic circuits,or to generate strongelectric fields for radiated immunity testing in TEM cells.It can generate up to 700V/m when driving the TekboxTEM Cell TBTCO,400V/m when driving the TBTC1,200V/m when driving the TBTC2,or 130V/m when drivingthe TBTC3.A built in AM-modulator enables the use of tracking generators as signal source.The TBMDA3B has sufficientgain to achieve its maximum output power when driven with the tracking generator of a spectrum analyzer.Besides 1 kHz,80%AM,the TBMDA3B provides built in modulation capability to generate 1 kHz,50%dutycycle PM signals.In PM mode,the TBMDA3B can also generate a 217 Hz Signal with 12.5%duty cycle in orderto simulate mobile phone TDMA noise.和TEKBOXRF.INPUTPicture 1-TBMDA3B modulated wideband driver amplifier,front viewPicture 2-TBMDA3B modulated wideband driver amplifier,rear view1
