    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...

    2.1 General Specifications Receiver Low Noise Amplifier (LNA) Operating Range: 2400-2483 MHz Receive Gain: 16 dB nominal Operating Mode: Bi-directional, half-duplex. Senses RF Freq Response +/-1 dB over operating range carrier from transmitter and automatically switches from receive to Noise Figure: 4 dB typical transmit mode.

    The use of the amplifier in any other combination (such as co-located antennas transmitting the same information) is expressly forbidden in accordance with FCC rules CFR47 part 15.204. Please visit our web site (www.ydi.com) to see the systems currently certified by the FCC.
  • Page 7 The picture to the left shows the amplifier in typical installation shown with the YDI Model PT2421 Grid Dish antenna vertically polarized. The location on the mast where the amplifier is mounted is not important: provided that the connectors face downward.

    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. This LED glows RED when the amp has switched to the transmit mode. Transmit LED: This occurs when the amp detects RF power at the jack labeled “To DC Injector”.

    DC-INJ-DUAL option is ordered. 8. Power Supply The AMP2440 kit comes with a 100 to 240 VAC power supply that has a standard 2.1 mm barrel plug [center pin positive (+) tip and outer ring negative (-)]. Although normally supplied with a power supply, any 12 Volt DC, 1 amp (or greater) regulated power supply can be used.

    9. Operation The unit operates automatically and there are no user adjustments. The amplifier is only intended for use with 2.4 GHz radio modems that alternate between transmit and receive in the same radio channel. These are referred to as Time Division Multiplex (TDD) devices.

  • Page 16 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.
