    PA100W RF Power Amplifier I. Precautions Working with RF power amplifiers can be dangerous and even fatal if not handled properly. Output voltages can reach values greater than 200 V peak-to-peak and can be fatal. Follow these steps to avoid damaging the amplifier or inflicting serious injuries.

    The PA100W power amplifier module measures 3.15" x 2.54" x 2.33" (80 x 65 x 59 mm). It can be delivered as a module (with the blanking circuitry) or in various enclosures - see the “Configuration Options”...

    100 MHz 1.56 Table 2 shows data for the PA100W when supplied by +28 V. The PA100W is capable of outputs greater than 100 W - however, it is important not to exceed the input power parameters for the specific operating frequency (Table 2) to avoid damaging the module. Also note that if the power amplifier is supplied by a +24 V DC source the gain is reduced and a maximum value of approximately 150 W PEP can be achieved.

    TTL values of 3.3V for a logical high, 0V for logical low. A logical high signal is required to deblank (enable) the PA100W. In testing, the TTL deblanking pulse is typically applied 300 us prior to the application of the RF pulse. The end of the deblanking signal coincides with the end of the RF pulse.
  • Page 9 PA100W RF Power Amplifier The timing diagram of a typical application of PA100W with the deblanking pulse applied prior to the RF pulse is presented in Figure 4, below. The top trace is the deblanking signal, the trace below represents the input signal, and the bottom trace is the RF output. In the lower panel, an expanded view of the RF output pulse is depicted.
