Simplify Your Test Setup |
|||||
The RF Test engineer is used to the idea of building their own feedback control system around the standard RF amplifier with a typical setup consisting of external dual directional coupler, power sensors, power meter, signal generator, with a PC running either their own custom code or heavily invested in customized Matlab or Labview coding. Besides this approach being a very slow feedback control loop, the cost of the system engineering and coding is high which results in a costly and lengthy development program. At the recent IMS show in Honolulu, Empower RF's CEO talks briefly about this topic and how a Smart amplifier can simplify your system hardware and software development. That the typical dumb amplifier actually operates in an open loop is the reason you have to build a closed loop around it. The dumb amplifier cannot be calibrated, requires a manual power lookup table, has a rollercoaster looking output vs. frequency curve, drifts with temperature, and doesn't measure accurately its own output power. Because of these shortcomings you have to build a control loop to make the amplifier work in your system.
