Wide Band Distribution Amplifier & Splitter with SMA Panel Mount Rear, SMA Short Connectors on Front, 500 KHz to 500 MHz

The DA500-E is a Wide Band Distribution Amplifier & Splitter with SMA Panel Mount Rear, SMA Short Connectors on Front, designed for 500 KHz to 500 MHz operation by Esterline Research and Design. The primary function of DA500 Distribution Amplifier is to distribute an existing signal to multiple points while preserving its integrity. The DA500 is ideal for situations requiring a low noise RF signal to be supplied to multiple usage points. 

The DA500 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 amplifier can be manufactured to support either 50Ω or 75Ω enivronments. This design provides multiple outputs of a modulated RF signal without the typical attenuation often associated with splitting of these types of signals. At most input frequencies, this results in amplification of the input, with the exception of the 450- 500Mhz range. At these highest frequencies, the attenuation is no worse than -2dB.

The single input is amplfied to compensate for the fanout to the five output stages. Each output stage has isolation transformers for impedance matching and channel-to-channel isolation. This configuration achieves high fidelity transmission of the input signal up to five usage points. 

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.
