1. Description The AMP2440 is a bi-directional amplifier designed for extending the range of 2.4 GHz wireless radio modems, Wireless LAN cards, Access Points and wireless bridges. The units provide transmit power amplification as well as receive signal gain. The amplifier is installed right at the antenna’s feed point, providing maximum effectiveness of transmit power. This has the effect of compensating for signal loss in the transmitter cable to the antenna.
NOTES: 2.1 General Specifications Receiver Low Noise Amplifier (LNA) Operating Range: 2400-2483 MHz Receive Gain: Operating Mode: Bi-directional, half-duplex. Senses RF carrier from transmitter and automatically switches from receive to transmit mode.
3. Amplifier Kit IMPORTANT: Only mount the amplifier with the connectors facing downward. Do not mount it with the connectors facing sideways or upwards. Each Amplifier Kit Includes: • • • • Bi-directional remote mounted amplifier DC Power Injector 12 VDC, 110/220 VAC Power Supply Stainless Steel U-Bolts and mounting bracket for amp • Installation Manual NOTE: 1. MPE distance figures are based on a conservative “worst case” prediction, i.e.
Safety Notice This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment when installed as directed. This equipment should be installed and operated with fix-mounted antennas that are installed such that the main lobe(s) of these antennas will have a minimum of 2 meters of separation distance between the antenna and all persons’ body during normal operation.
5. Amplifier Connections and Indicators CAUTION: Only use high quality N-type connectors. Do not use PL259 “CB” type UHF connectors. Doing so will ruin the N-Female jacks and void your warranty. Transmit LED: Receive LED: DC Injector Connection: Antenna Connection: This LED glows RED when the amp has switched to the transmit mode. This occurs when the amp detects RF power at the jack labeled “To DC Injector”.

3. Amplifier Kit IMPORTANT: Only mount the amplifier with the connectors facing downward. Do not mount it with the connectors facing sideways or upwards.
NOTE: 1. MPE distance figures are based on a conservative “worst case” prediction, i.e. +24 dBm into antenna using formula S=EIRP/(4piR2) and no calculaton for duty factor. In practice the minimum distance will be much shorter. 2. The minimum MPE distance has been calculated for the maximum allowed Power Density (S) limit os 1.0 mW/cm2 in the Frequency range 1500 - 100,000 MHz for uncontrolled environments (Ref. 2).
