Fairport, NY. Saelig Company Inc. announced that it is offering the TekBox TBMDA2/TBMDA3 modulated wideband power amplifiers, which are designed to create an inexpensive signal source for precompliance immunity testing of electronic PCBs and products. Driven by the tracking-generator output of a spectrum analyzer, they provide the increased RF power outputs required by many test environments. With an input power range of up to -8 dBm /0 dBm, these amplifiers can boost the output power of a tracking generator up to 500 mW/5 W or 40 dB from 10 MHz to beyond 1 GHz.
In addition to other applications, the TBMDAx amplifiers are suitable for driving TekBox near-field probes in order to detect problem areas of an electronic circuit or to create electric fields up to 550 V/m when driving TekBox TEM cells. Test signals for immunity testing can be CW or AM/PM-modulated. These amplifiers include built-in modulation capabilities to generate 1 kHz AM or PM signals. In PM mode, the TBMDAx amplifiers can also generate a 217 Hz Signal with 12.5% duty cycle in order to simulate mobile-phone TDMA noise.
The TBMDA2 is powered by external 5 V and consumes about 3.5 W, and the TBMDA3 is powered by external 100 to 240 V and consumes 20 W.
