![]() TekBox TBMDA4 Modulated Power AmplifierManufacturer: TekBox Digital Solutions This product has been superseded by the TBMDA4B.
The TBMDA4 modulated wideband power amplifier has been designed to provide an inexpensive signal source for immunity testing of electronic building blocks and products. It is intended to be driven by the tracking generator output of a spectrum analyzer. With an input power range of -5dBm to 0dBm, it can boost the output power of a tracking generator up to 5W. With a frequency range from 100kHz to 50MHz, it complements the similar TBMDA3 whose range covers 10MHz to 1GHz. The TBMDA4 is ideal for driving Tekbox near-field probes in order to find sensitive spots of an electronic circuit, or for creating strong electric fields when driving Tekbox TEM Cells: TBTC0 (up to 550V/m ), TBTC1 (300V/m), TBTC2 (150V/m), or the TBTC3 (100V/m). Test signals for immunity testing can be CW, AM or PM modulated by the TBMDA4, which provides the built-in modulation capability to generate 1kHz AM or PM signals. In PM mode, the TBMDA4 can also generate a 217 Hz Signal with 12.5% duty cycle for simulating mobile phone TDMA noise. Application
