Functional Description:
The function of a distribution amplifier is to create multiple copies of a signal while minimally degrading its integrity. The DA100 distribution amplifiers are designed to distribute a low-noise RF signal to multiple usage points, where equipment requiring such signals may be employed.
The DA100 has one input and five outputs. It may be configured with either SMA or BNC connectors (see Options Section for more information). The input is AC-coupled, offers an input source impedance of 50 Ω, and is conditioned by a limiter circuit, which provides a fixed output level as well as high input gain. The high input gain allows the amplifier to provide the specified output power over a broad range of input power.
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 minimizes channel-to-channel phase offsets (<1 ns); the phase offset from the input to any output is less than 5 ns at 10 MHz.
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..
