Tekbox TBMDA7 Modulated Wideband Driver Amplifier

Tekbox TBMDA7 Modulated Wideband Driver Amplifier

The Tekbox TBMDA7 is a modulated wideband driver amplifier, The device 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 to 3 GHz and is designed to be driven by the tracking generator output of spectrum analyzers. With a 1 dB compression point of 350 mW average and a saturated output power of 500 mW average, 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 when driving for example the Tekbox TEM cell. 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.
