Description: Item Description: Fall Sale. For sale today is one 10MHz isolated distribution amplifier board with four outputs for use with an OCXO, GPSDO, or Rubidium source. This board has BNC connectors vertically on the back side for ease of mounting to a rack panel. This board has 1" between the four output BNC connectors. The BNC connectors are name brand (currently AMP/TYCO) not the cheap Chinese stuff. Nuts and washers for the BNC connectors are included. Condition: This is a new (for now hand assembled) board that will take a 0dBm sine wave input and produce four 50 ohm isolated 0dBm outputs. The input is 50 ohms and is also isolated from the board electronics. 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 and the input has a series diode, so a well regulated 12V supply could also be used. All noise and harmonics are down more than 60dB from the output at 0dBm and 55dB at 10dBm provided the input 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. A square wave can also be used as input provided the voltage is about 0.6V P-P (with 5VDC supply) or 2V P-P (with 10VDC supply). A resistor in series with the input can be used to reduce the voltage if needed. The board is approximately 2.65" by 3.7". The layout with dimensions for the rear mounted BNCs is provided in the pictures, as seen from the top side of the board. Dimensions are in MIL (1/1000 inch). The layout dimensions are also on the side that has the BNC connectors. The BNC connectors can be used to hold the board to a panel. Unlike other units that share a common driver between outputs, this board has individual drivers for each output. This prevents one output from affecting the others.
