DA100-6 Low Noise 5 Channel 10 MHz Dist Amp. w/ Bulkhead SMA Connectorsby ER&D $ 499.43
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.

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.
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.
Calibration Service Option:
Includes verification that device meets all manufacturer specifications. If device has adjustments, the device's performance is optimized. If the device is not operating within specified limits and can not be adjusted to do so, the customer is notified, and a cost estimate to repair the device will be issued. If the device is under warranty and the non-compliance to manufacturer specifications is due to a fault covered under warranty the device will be repaired or replaced. One, three, and five year plans are available for purchase.
Extended Warranty Option:
Extended warranty option provides an additional two years of 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.
