  • Page 22: Sspa Module

    HPOD C-, X-, Ku-Band High-Power Outdoor Amplifier Revision 9 1.4.1 SSPA Module The amplifier module performs the core function of the unit. An isolator is at the RF input to ensure good VSWR. The RF signal then passes through an input sample port and on to an electronically controlled attenuator that adjusts the overall attenuation according to the user input.

  • Page 23: Block Up Converter Input Option

    Unlike most BUCs, no DC bias voltage should be provided on the center conductor of the L-Band coax. In addition, the BUC version of the HPOD is available with an internal 10 MHz reference. As, such, no 10 MHz reference is required on the center conductor of the L-Band coax. If a reference is provided on the coax, the internal reference will detect and lock to it.

  • Page 75: Attenuator Control

    The Mute command provides over 60 dB of RF on/off isolation. However, the Mute command only turns off the first few low power stages of the amplifier, the high-power stages remain on. By allowing the higher power transistors to stay on, the HPOD remains in a more thermally stable state should the mute condition be removed.

  • Page 76: Power Detector

    5.2.5 Power Detector The HPOD features a power detector to monitor the output power. It has a useful range of over 20 dB, referenced to the unit’s rated P1dB point. To read its value, execute the “RMS” query (e.g., <1/RMS?<cr>). The test data supplied with each unit gives an indication of the accuracy and flatness of the power monitor over the frequency band of operation.
