Electronics Support Switching Unit (ESSU) designed, built, and tested by R. A. Wood Associates

R. A. Wood Associates designed, built, tested, and delivered 2 Electronics Support Switching Units (ESSU) to one of our customers. This was another set of hardware slated to to be installed on a Navy Vessel. The ESSU was designed to be installed between the front end (Antennas, RF amplification switching, filtering) and back end (RF processing) of a complex RF/Microwave system. The purpose of the ESSU was to allow a second front end (RF Subsystem 2) to be switched into the same back end, to make use of the RF signal processing in the back end.

Some of the major components in the ESSU are as follows:
  • Wideband RF/Microwave amplifiers
    • Our Extreme BW RF amplifier was used in this design for the low frequency, wide bandwidth RF path
  • Equalizers and attenuators to align the RF paths
    • Some vendor purchased equalizers were used
    • R. A. Wood Associates equalizers were also used where vendor equalizers were not available
  • Terminated mechanical RF switches (50 ohms)
  • Terminated mechanical RF switches (75 ohms)
  • HDRFI external RF interface to save RF connector space
  • DC power conditioning
  • FPGA card to control switches and provide Built-in-test (BIT) status
  • LED displays for BIT and switching status
  • Custom designed audio switching board
