The TBMDA3B, 10MHz – 1 GHz modulated broadband power amplifier is designed to provide a low-cost RF power source for immunity testing of electronic building blocks and pre-conformance products. Operated at an input power of less than 0 dBm, it can deliver a saturated output power of up to 8 W.
TBMDA3 is ideal for driving Tekbox near field probes to find the sensitive point in electronic circuits, or to generate strong electric field for radiated immunity testing in TEM cells. It can generate up to 700V/m when running Tekbox TEM Cell TBTC0, 400V/m when running TBTC1, 200V/m when running TBTC2 or 130V/m when running TBTC3.
A built-in AM modulator enables the use of tracking generators as a signal source. The TBMDA3B has sufficient gain to achieve its maximum output power when driven with the tracking generator in a spectrum analyzer. In addition to 1 kHz, 80% AM, the TBMDA3B has built-in modulation capability to generate 1 kHz, 50% duty cycle PM signals. In PM mode, the TBMDA3B can also generate a 217 Hz signal with 12.5% duty cycle to simulate TDMA noise from mobile phones.
