DA100 Operation Manual

Functional Description:

The primary function of our DA100 distribution amplifier is to distribute an existing signal to multiple points while preserving its integrity. The DA100 is ideal for situations requiring a low noise RF signal to be supplied to multiple usage points.

The DA100 has one input channel and five output channels. It may be configured with either SMA or BNC connectors (details provided in the connector table on page 4). The input is AC-coupled and has a 50 Ω source impedance. It includes a limiter circuit that not only provides a fixed output level but also offers high input gain. This design allows the amplifier to maintain the specified output power across a wide range of input power levels.

The input limiter is followed by three amplifier/low-pass filter stages, which insure low-distortion sine wave outputs. The outputs from the filter stages are supplied to fixed-gain output amplifiers. This configuration achieves channel to channel phase offset of under 1 ns; the phase offset from the input to any output is less than 5 ns at 10 MHz.

For larger systems requiring more outputs, multiple amplifiers may be daisy-chained together by connecting the output of channel five to the input of another distribution amplifier. However, this configuration increases phase offset between amplifiers. If channel-to-channel phase offset is a concern, the recommended configuration would be to use a single amplifier to drive up to five additional amplifiers. This will provide up to 25 outputs with minimal channel-to-channel phase offset.

Notes:

1.) Input signal waveform can be any type with a 50% duty cycle.

2.) The device may be powered with a user-supplies voltage via the screw terminal connections or by the 2.1 mm plug on the included 6 V, 500 mA power module. When the power module is utilized, the module voltage is made available on the screw terminals, thus allowing the user to access 6 V, 250 mA to power external circuitry. 

Caution: Do not connect an external supply voltage to the screw terminals when using the power module.

Warranty:

Device comes standard with a one-year manufacturers warranty.  Faulty devices will be repaired or replaced if they are defective due to a manufacturing defect.  Misuse or operation outside of the stated limits above will void warranty.  Damage caused by such misuse or operation outside of specified limits will not be covered under warranty.
