Microwave Antenna Radiation Warning Designed for point-to-point operation, a Link AX microwave radio system uses directional antennas to transmit and receive microwave signals. These directional antennas are usually circular or rectangular in shape, and are usually mounted outdoors on a tower or mast,well above ground level. Referencing OET Bulletin 65 (Edition 97-01,August 1997)from the Federal Communication Commission ’s Office of Engineering &Technology, limits for maximum permissible exposure (MPE)to microwave signals have been adopted by the FCC for General Population/Uncon- trolled environments. This limit is 1.0 mW/cm 2 ,with averaging times of thirty-minutes. The closer you are to the front center-point of a microwave antenna,the greater the power density of its transmitted microwave signal.Unless you are very close,however,microwave exposure levels will fall far below the MPE limits.To determine how close to a microwave antenna you can be and still remain below the MPE limits noted above,“worst case ” predictions of the field strength and power density levels in the vicinity of an Link AX ™ microwave antenna can be made from the following calculations. The equation is generally accurate in the far-field of an antenna, and will over-predict power density in the near-field (i.e.close to the antenna). S =PG/4πR 2 where:S =power density (in mW/cm 2 ) P =power input to the antenna (mW) G =power gain of the antenna in the direction of interest relative to an isotropic radiator R =distance to the center of radiation of the antenna (cm) Note that G,the power gain factor,is usually expressed in logarithmic terms (i.e.,dB),and must be converted using the following equation: G =10 dBi/10 For example,a logarithmic power gain of 17.5 dB is equal to a numeric gain of 56.23. Assuming (1)maximum output power from the Link AX (+12 dBm [15.8 mW ]),(2)no signal loss in the cable connecting the Link AX to the antenna,and (3)the use of a 17.5 dBi gain flat panel antenna,the 1.0 mW/cm 2 MPE power density limit would be reached at a distance of approximately 8.4 cm. The Link AX is classified as a fixed installation product ,and per FCC policy guidelines regarding MPE, antennas used for this Wireless Inc. transmitter must be installed to provide a separation distance of 1.5 meters (5 feet)or more from all persons during normal operation to satisfy FCC RF exposure compliance. Wireless,Inc. fully supports the FCC ’s adopted MPE limits, and recommends that personnel maintain appropriate distances from the front of all directional microwave antennas. Should you have questions about Link AX microwave signal radiation, please contact the Wireless, Inc. Customer Service Department.

NOTE: After switch settings are entered, the screw-on cap is permanently attached using LOK TITE adhesive, to deny user access to the settings.

9 WaveNet Link AX Installation and Operations Manual 2.5Theory of Operation General Overview The Link AX is a point to point Wireless ATM-25 Extender operating in the 5.3/5.7 GHz U-NII band as authorized in rule sections 15.401 through 15.407. The unit is enclosed in a weather proof outdoor enclosure and is intended to provide data links over distances up to 15 km. The radio in the unit operates full duplex, transmitting and receiving data at the rate of 8.192 Mbps. The radio is modulated using BPSK. Circuit Description The following circuit description is intended to explain the operation of the radio at the block diagram level. This text is written with the idea that the reader has the block diagram readily available, as it will aid in understanding the signal flow in the radio. 2.5.1 Link AX Transmitter The physical interface to the radio consists of ATM-25 cells that are routed to ATM physical interface (PHY) chip. The PHY chip stores the data cells, and then converts them into a synchronous 8.448 Mbps data stream that is fed into the transmitter. To mark cell boundries, a SYNC byte (01111110) is inserted at the beginning of every cell. Zero insertion circuitry, inserts a zero after five consecutive ones, guaranteeing SYNC byte uniqueness while transmiting the cell’s content. The data is differentially encoded and scrambled before it is routed through the transmit baseband filter to provide spectral shaping. The baseband filter is a five pole low pass filter. After amplification, the baseband signal is fed to the modulator consisting of a doubly balanced mixer. The modulator is running directly at the transmitter frequency of 5.775 GHz ± 50 MHz. The local oscillator signal of the mixer is supplied from the frequency synthesizer section, with the frequency dependant on the RF channel selected. From the output of the modulator, the signal is amplified and then passed through a 150 MHz wide bandpass filter to remove any local oscillator products from the output spectrum. After filtering, the signal is passed through a series of amplifier and attenuator stages that are used to control the output power level. With a combination of fixed and variable attenuation the output power can be set to one of four different levels to accommodate different antennas used with the product. The power setting is maintained by an active ALC circuit that samples the transmitter output power and then adjusts the variable attenuator to keep the output power constant over the operating temperature of the unit. The power level is controlled to within +1/-2 dB of the set point. Following the attenuators the signal is fed through additional amplification to bring the output level to a maximum of +14 dBm at the output of power amplifier. A lowpass matching section follows the power amplifier to aid in filtering harmonics of the signal. After passing through the duplexer, the power level at the antenna port is a maximum of +12 dBm. 10 WaveNet Link AX Installation and Operations Manual Figure 2.2a - Outdoor Unit, Front View, External Antenna Figure 2.2b - Outdoor Unit, Back View, External Antenna WL293001 DIP Switch Access Antenna Connection (N Type, Female) ODU Ground Connection Mounting Studs WL292002 Receive Signal Strength Indicator (RSSI) (BNC Type, Female) Siamesed Category 5 ATM and Power cables connections 11 WaveNet Link AX Installation and Operations Manual ODU Ground Connection Mounting Studs WL291003 Receive Signal Strength Indicator (RSSI) (BNC Type, Female) Siamesed Category 5 ATM and Power Cables Connections DIP Switch Access Figure 2.2c - Outdoor Unit, Front View, Integral Antenna Figure 2.2d - Outdoor Unit, Back View, Integral Antenna Outdoor RF unit with integral Antenna WL241008 12 WaveNet Link AX Installation and Operations Manual 2.5.2 Link AX Receiver The receiver in theLink AX is a conventional dual conversion design with IF frequencies of 474.88 MHz and 70 MHz. From the receive port of the duplexer, the low level input signal is passed through a low noise preamplifier that provides 25 dB of gain. Following the preamplifier the signal is passed through a 200 MHz wide bandpass filter to provide image rejection for the first mixer. The signal is then mixed with the first LO to convert the signal to 474.88 MHz. Following further amplification the signal is passed through a five pole, 20 MHz wide bandpass filter. This filter provides image filtering for the second mixer, and also helps attenuate signals on the adjacent receive channels. After filtering, the signal is further amplified and then passed through a variable attenuator stage before it is applied to the second mixer. The output of the second mixer is at 70 MHz. The 70 MHz IF stages provide additional gain along with two sections of variable attenuation for the AGC function. The primary adjacent channel filtering is also at 70 MHz where the signal is passed through a 12 MHz wide SAW filter. The combination of filters provide a minimum of 47 dB of attenuation at the adjacent receive channels (±10.24 MHz). At the end of the 70 MHz IF chain the signal is fed into a quadrature demodulator. The carrier recovery loop consists of a four quadrant multiplier that multiplies I and Q baseband signals to create an error voltage. This error voltage is then amplified and fed back to the 70 MHz VCO. This forms a phase locked loop that is locked to the received carrier frequency. The 70 MHz output is also fed into a wide band logarithmic amplifier that provides a DC voltage output proportional to the 70 MHz signal strength. The DC voltage is then integrated and fed back to the variable attenuator stages to form an AGC control loop. This control loop keeps the signal level at the input to the demodulator chip constant over the entire operating range of the receiver. Data recovery from the I baseband signal begins by passing the I signal through a slicer. The output of the slicer is a digital signal that contains both data and clocking information. A cloc…
