TekBox TBMDA1 Modulated Wideband Driver Amplifier

The TBMDA1 modulated wideband driver amplifier is an inexpensive signal source for immunity testing of electronic building blocks and products. It is designed to be driven by the tracking generator output of spectrum analyzers. With its gain of 22 dB and 1dB compression point of +22dBm, it can boost the output power of a tracking generator up to 150mW over a range of 20MHz to 3GHz. The TBMDA1 is ideal for driving the Tekbox Near Field Probes in order to find the sensitive spot of an electronic circuit; or for creating electric fields up to 50V/m when driving the Tekbox TEM Cell TBTC1, 25V/m when driving the TBTC2 or 18V/m when driving the TBTC3. Test signals for immunity testing can be CW, AM or PM. Consequently, the TBMDA1 provides built in modulation capability to generate 1kHz AM or PM signals. In PM mode, the TBMDA1 can also generate a 217Hz Signal with 12.5% duty cycle in order to simulate mobile phone TDMA noise.

Application:

• Pre-compliance RF immunity testing, driving Tekbox EMC probes or TEM cells
• RF driver amplifier
• General purpose wideband RF amplifier
