TekBox TBMDA7 Modulated Wideband Driver Amplifier

The TBMDA7 modulated wideband driver amplifier is designed to provide an inexpensive signal source for immunity testing of electronic building blocks and products. It operates in the frequency range from 1 GHz to 3 GHz and is designed to be driven by the tracking generator output of spectrum analyzers. With a 1dB compression point of 350 mW avg. and a saturated output power of 500 mW avg., it can boost the output power of a tracking generator to drive Tekbox near field probes in order to find the sensitive spot of an electronic circuit or to create electric fields up to 150V/m CW, 80V/m AM when driving the Tekbox TEM Cell TBTC 0, 80V/m CW, 45V/m AM when driving the TBTC1, 40V/m CW, 25 V/M AM when driving the TBTC2 or 27V/m CW, 15V/m AM when driving the TBTC3. Test signals for immunity testing can be CW, AM or PM. The TBMDA7 provides built in modulation capability to generate 1 kHz AM or PM signals. In PM mode, the TBMDA7 can also generate a 217 Hz Signal with 12.5% duty cycle in order to simulate mobile phone TDMA noise.
