10MHz Isolated Distribution Amplifier Expander Board w/4 outputs

Description: Item Description: For sale today is one 10MHz distribution amplifier expander board with four outputs for use with my 4 channel distribution amplifier board (in another listing). This board has 1" between BNC connectors. It matches the spacing of the distribution amplifier board that is currently listed on EBAY. The 2 pin connector (and pigtail wires) to bridge the 10MHz from the main board to the expander board is included. See the 3rd picture for locations on the main board to solder the two wires. This board will not function properly without the DC bias provided by the main distribution amplifier board. The expander board may be mounted above the main board or off to one side if on a wide panel. The power for the board is wired in parallel with the power to the main board on a screw terminal connector. The BNC connectors are name brand (currently AMP TYCO). Nuts and washers for the BNC connectors are included. The main distribution amplifier board and the spectrum analyzer in the pictures are not included in this auction. Condition: This is a new (for now hand assembled) board. Power required is a minimum of 5VDC at under 50mA. The maximum input level with a 5VDC power supply is 6dBm. The power supply is not included. With a 10V power supply, the board can take up to 10dBm at the input and produce four 10dBm outputs. The op-amps are rated for 12.5V max, so a well regulated 12V supply could also be used. All noise and harmonics are down about 50dB from the output at 0dBm and at 10dBm provided the input and power limitations are followed, see the last two pictures. The pictures were made with a 10dB attenuator between the output and the spectrum analyzer so the actual output levels are 10dB higher than displayed. The board is approximately 1.65" by 3.9". The layout (with dimensions for the BNC connector centers) is provided in the pictures, as seen from the top side of the board. Dimensions are in MIL (1/1000 inch). The BNCs can be used to hold the board to a panel. This board (and the main board) with the horizontally mounted (white) BNCs will fit on an enclosure front panel with a panel width of at least 4 inches such as a Hammond Engineering 1455N1202 enclosure available at Mouser or Digi Key. The boards will slide in on the groves on the inside of the enclosure.
