This device cannot be used with any transmitter other than the one it has been supplied with. This device requires professional installation. User is responsible for compliance with applicable laws and regulations Installation and Operation Manual The entire transceiver station assembly consists of seven main components: 1.Low-noise receive amplifier, transmit amplifier, bandpass filter, and switching control unit assembled in a sealed enclosure. 2. DC power injector. The power injector connects to the transmitting device and the amplifier assembly with a 10 ft. RF 50 Ohm coaxial cable. 3. 110-220 VAC Power supply with DC output BNC connector. 4. 10 ft. 50 ohm RF cable assembly. 5. One of 4 antenna models (omni, yagi, dish) as appropriate for installation. 6. Lucent Technologies Model: PC24E-00-FC WaveLAN 2.4 GHz wireless PCMCIA card. 7. Computer system. The amplifier kit contains the following equipment: ItemQuantity Amplifier1 DC Power injector1 Power supply1 Mounting brackets1 U-bolt1 Installation Instructions Important Notice: Read the following installation instructions and all warnings carefully prior to installing the amplifier. Failure to follow installation instructions or tampering with the amplifier or the power supply will void the warranty. 3 1. Install the amplifier on a mast near the external antenna, using a U-shaped bracket (included). The amplifier can be installed vertically or horizontally. 2. Connect the side of the amplifier labeled “Modem” to the DC power injector, and the side labeled “Antenna” to a surge protector (not included) with the 10 ft., 50 Ohm coaxial cable. Important: In order for the amplifier to operate properly, and to avoid damage to the amplifier and the power supply, the maximum input power to the amplifier must not exceed 100mW. User must check for proper attenuation. 3. Connect the DC power injector to the external antenna port of the wireless modem card via a 50 Ohm coaxial jumper cable (included). 4. Following installation, a weather sealant must be applied to all external connectors to protect them from moisture (moisture can cause increased signal losses in the feeder, diminished transmission quality, and possible damage to the connectors and the amplifier). 5. Grounding. Ensure that the mounting mast is properly grounded. Check the ground on the amplifier assembly with a Ω-meter. 4 Warning: Improper grounding can adversely affect amplifier performance and may lead to equipment damage or personal injury. Failure to properly ground the amplifier will void the warranty. The amplifier does not have built-in surge protection, and is not designed to withstand a lightning strike. Use of a surge protector is highly recommended for outdoor installations. Amplifier warranty does not cover damage caused by lightning or static electricity. Operation of the Amplifier • On power up, the amplifier will be in a "receive" mode. The mode switches to "transmit" when the amplifier receives a signal from a radio modem. A Green light on the DC injector indicates that the amplifier has power. A red light on the DC injector indicates that the amplifier is in a "transmit" mode. The red light blinks when the amplifier is connected to a bi-directional RF device. • A constant red light indicates that the amplifier is continuously in "transmit" mode and is not communicating properly. This is an abnormal condition that can be caused by any of the following: - High noise level in the feeder of the transmitting device. With time, some radio modems develop elevated natural noise levels, even in the "receive" mode. This noise can cause the amplifier to switch from "receive" to "transmit" mode, causing interruptions in communications. If this problem is detected, the transmitting device should be replaced. - External interference. If the amplifier is not properly grounded, external interference can cause the amplifier to intermittently switch to "transmit" mode. This condition has been observed with some radio modems, due to the modems' poor shielding characteristics. Thus, if the transmitting device is not adequately shielded, several such devices operating in close proximity can interfere with the amplifier's operation. • If t…

Block diagram description of the Lucent WaveLAN PC Card 2.4GHz, High Speed 1 WaveLAN PC Card 2.4 GHz High Speed DESCRIPTION OF THE BLOCK DIAGRAM The various parts of the Block diagram are numbered and an explanation is given of these blocks. First the transmitter will be described: A) Digital Signal Processor. (22) Function : Generate spreaded signal with an Barker sequence of 11, the original raw data rate of 1, 2, 5.5 or 11 Megabits is transformed to a symbol rate of one MegaBaud and multiplied with eleven and modulated with a DQPSK ( Differential Quadrature Phase Shift Keying ) Modulation for 1 and 2 Mbps or DQPSKCCK (CCK = Complementary Code Keying) for 5.5 and 11 Mbps. The unfiltered data comes out of I and Q and goes to the up/down mixer (6) B) The above signals are mixed in (6) in a so called quadrature modulator with the Intermediate Frequency ( IF) of 352 MHz. C) The upmixer is fed by the VCO of 704 MHz, which is divided by 2 to 352 MHz. D) The SAW ( 8 ) filters all unwanted mixing products, such that only the 352 MHz band remains. E) This signal goes into the RF upmixer ( 9) SA2420 were it is mixed with the RF VCO with a range of 2050 to 2150 MHz. F) The Rx/Tx switch (17) brings the signal to the variable attenuator (10 ), where the output level is controlled. G) The signal is fed through a 2.4- 2.5 GHz bandpass filter (11) to remove all unwanted mixer products, and thus to get a clean signal for further processing. H) The signal is amplified in (12), with approx 23 dB to an output level of approx. 15 dBm I) This signal goes to the RX/TX antenna (23/24) via the special connector with a switch inside to disable the antenna. J) The output power is controlled with a so called power feed back loop (15) in which the output power is compared with a DAC value from (10) Receiver functions. K) The receive signal enters the antenna passes the RX/TX switch (14) and (13) this is set to RX mode. L) The signal goes through the 2.4 GHz filter (16) to remove all unwanted spectral components in order to deliver a clean signal for the receiver. M) A Low Noise Amplifiers (LNA) (in 9) is used to amplify the weak signal to a level fitted for down mixing. N) The AGC (27) can amplify or attenuate the signal according to the Digital signal processor required input with a step size of 26 dB. O) Again the Rx/Tx switch in the Rx mode is passed and also the same filter as in transmit mode ( 18). P) The down mixer (9) mixes the 2.4 GHz with the 2.1 GHz to the 352 MHz IF. Q) The signal of 352 MHz is amplified again (9) and filtered by a SAW filter (19) to give a clean signal for the second mixer. Block diagram description of the Lucent WaveLAN PC Card 2.4GHz, High Speed 2 R) The Downmixer (6) mixes the 352 MHz signal down to the I and Q signals, also the auto gain control can increase the level to the required level via line 20. S) The very low amplitude baseband I and Q signal is amplified in the AMPs (6) to a level fitted for the Analog to Digital converters (22), which make it a proper signal for the digital signal processor. T) The digital signal processor (22) removes the spreading as present on the signal with a so called autocorrelation function. The resulting output of the processor is a received data rate of 1, 2, 5.5 or 11 Megabits. VCO , PLL and OSC. U) These three form one entity to generate a single tone signal for down mixing. There are two of these blocks available, one for the IF LO (7 and 6 ) (352MHz ) and one for the RF LO (25 and 26) of 2050 to 2150 MHz. V) All the PLL’s and the processor (2) have one reference Crystal of 22 MHz (4) with an accuracy of 25 ppm. General circuits: W) Antenna Diversity. This functin may be placed on the radio board or on extended board (as part of external antenna. Depending on the signal strength and signal quality the Digital processor (22) can choose between the two antenna’s (23) and (24) which gives the best signal. This is done initial during the training sequence in the received signal. X) Automatic Gain control. Depending on the signal strength and signal quality the Digital processor (22) can choose to increase or decrease the signal level at the digital input, this is done by reducing or increasing the gain in the receiver via the LNA-AGC (in 9). Y) The Signal processor (22) can read via the MAC (2) the registers for programming all parameters for transmit/receive functions Z) The MAC is used to do the handshaking with the PCMCIA bus (1 ) and handling the IEEE protocol. Also used to load the PLL frequencies and dividers, also used to interface to the FlashROM which contains all parameters for the PLL’s and the Callcode. AA) Not shown is the regulator to supply the 3.3 Volt out of the 5 Volt out of the PCMCIA Bus (1) Guus Jansen Rev.
