Thanks to this handy kit, building a high performance 5.8GHz
A/V receiver has never been easier. The kit provides a
custom printed circuit board set and quality electronic
components.
NOTICE: This kit requires assembly and is NOT
recommended to beginners. It is suitable for amateur radio
hobbyists, RF technicians, and engineers. The builder must
have good quality soldering tools, an anti-static work
environment, and electronic assembly experience.

  • Page 1 AV680RX 5.8GHZ A/V RECEIVER KIT Rev-B Kit INTRODUCTION Thanks to this handy kit, building a high performance 5.8GHz A/V receiver has never been easier. The kit provides a custom printed circuit board set and quality electronic components. NOTICE: This kit requires assembly and is NOT recommended to beginners.
  • Page 2 Install C4, C6, C8, C10 (470uF caps). Figure 2 Caps, Resistors, and Inductors. Install R5 and R6 (2.2 ohm resistors). Install R4 (220 ohm resistors). Install R1, R2, and R3 (3.3K ohm resistors). Install L1 (27uH Inductor). AV680RX-Kit, Rev-B Page 2 © Nov-03-2008...
  • Page 3 Figure-5, then it may be necessary to file its metal mounting tabs Note: The SMA-RP connector is shown in the photo for reference only. Do NOT install it at this time. Figure 5, RF Module Installed AV680RX-Kit, Rev-B Page 3 © Nov-03-2008...
  • Page 4 Carefully solder the three ground legs and the center post, as shown in Figure 7. Ensure the module’s metal enclosure is not shorted to the center post conductor. Clean off ALL flux, even if no-clean solder was used. Perform a visual inspection (do NOT use an ohmmeter). AV680RX-Kit, Rev-B Page 4 © Nov-03-2008...
  • Page 5 Do not use the SMA-RP connector when installing dpcav.com’s #AWM5.8ANT economy patch antenna (available separately). Instead, directly solder the coax to the RF port. See Figure 8. Warning: While soldering, do not disturb the tiny SMD component installed on the input pad of some RF modules.
  • Page 6 5820 5840 5860 ON = Switch closed (Down position) OFF = Switch open (Up position). Note: The forth DIP Switch (SW4) is NOT used and should be ignored. Figure 10, Freq & Audio Config. AV680RX-Kit, Rev-B Page 6 © Nov-03-2008...
  • Page 7 A/V jacks are used. If the brightness is affected too much then it will be necessary to use only one A/V jack and an external video amplifier such as our #PLV2-001. Figure 12, A/V Plug Details AV680RX-Kit, Rev-B Page 7 © Nov-03-2008...
