Features such as high linearity power amplifiers are contributing for the overall improved system linearity performances. The unit is based on a duplexed path configuration, having sharp out of band attenuation for improved isolation between the receiving and transmitting paths. BLOCK DIAGRAM DESCRIPTION: The Repeater Downlink path receives the RF signals from base station, amplifies them and transmits them to the subscriber. The Repeater Uplink path receives the RF signals from the subscriber, amplifies them and transmits them to the base station. Two duplexers frequency separate the signals to the proper amplifying path and isolate the two signals. For each path two amplifiers do the path signal amplification; a low noise amplifier (LNA) and a high power amplifier. The low noise amplifier has a 30 dB step attenuator to set the gain of the specific path. REPEATER (BDA) CONNECTION The RF connection is made via two type “N” female connectors. The RF connector labeled “Base” must be connected to the antenna pointing to the base station; usually a rooftop antenna. The RF connection labeled “Mobile” must be connected to the antenna pointing into the area to be covered by the Repeater such as inside a building or outdoor shaded area.

If the Repeater gain were higher than the isolation between the antennas, oscillation would start and would saturate the amplifier. Isolation few dB higher than the Repeater gain cannot start oscillations but would cause gain ripple in the band. The step attenuator on the low noise amplifier reduces the Repeater gain. The Repeater gain can be stepped down by the amount indicated on the step attenuator. AGC FUNCTION The Repeater has AGC function on both paths that serve to prevent the saturation of the power amplifier. When a high signal is received the AGC circuit detects the amplitude and sends a feedback signal to a variable attenuator, which attenuates the signal level so that the output power of the amplifier does not exceed the preset limit. The green LED on the BDA monitor (AGC Range) illuminates when the power output of the amplifier is within the set limit. An On/Off switch on the connection box enables the AGC function. If the AGC is disabled then the amplifier gives maximum gain.

For the downlink channel a red fault LED illuminates if the power is 10 dB below the specified composite power. In normal use the downlink channel continuously transmits RF signals and this LED should be on. When the donor reception from the base is bad this LED turns on to warn that the repeater is not being used efficiently. Another green LED illuminates when the power reaches or exceeds this power (10W). This is used to set the repeater gain. This limit is the same as the AGC limit and is factory preset. For the uplink channel a green indicator LED illuminates when the power reaches or exceeds its composite power (1W). When the isolation between the antennas is bad this LED lits permanently. This LED should turns on only when a near by cellular is used. This limit is the same as the AGC limit and is factory preset. DC voltage of the channels. The fault LED illuminates when the voltage is below or above the specified limits. DC current to each of the two LNAs and the uplink power amplifier.

The power amplifier has a directional coupler and a detector at its output to monitor the output power. When a high signal is received the automatic level control detects the amplitude and sends a feedback signal to a voltage variable attenuator, which attenuates the signal level so that the output power of the amplifier does not exceed the preset limit. The LED on the amplifier illuminates when the power output of the amplifier is within the set limit (when the AGC is On and when the AGC is OFF). An On/Off switch enables the AGC function. If the AGC is disabled then the amplifier gives maximum gain. BDA MONITOR The BDA monitor monitors the DC voltage of the channels. The fault LED illuminates when the voltage is below or above the specified limits. The monitor box also monitors the current to each one of the 4 amplifiers. If the current is below or above the specified limits then a LED illuminates. FAULTS LIST (up link & down link) P.S. Illuminates when the Power Supply voltage is below or above its limits. P.AMP. Illuminates when the Power Amplifier current is above or below its specified limits. Note : The downlink amplifier will trip a fault when overdriven by RF signals. L.N.A. Illuminates when the Low Noise Amplifier current is above or below its specified limits. FAN Illuminates when the internal FAN current is above or below its specified limits. N.C. Not connected. (Future option) A pushbutton switch on the BDA monitor turns on all the alarms. This is used to test the alarm functions of the BDA. REMOTE ALARM The BDA monitor has a dry contact relay arms output. These contacts are short circuit at no fault and open circuit at any fault or when the power is off. This function can be used to operate a modem for remote alarm warning. The relay contacts are connected to pins A and C (small pins) on the alarm connector at the front panel.

This antenna is installed outdoor and has very sharp beam (Yagi type or similar) pointed to the donor (BTS). This type of antenna has about 10 dBi gain. Typical specifications: gain: 8 dBd (=10.1 dBi), VSWR: better than 1.5:1 , Impedance: 50 ohm. The outdoor antenna must be installed to provide a minimum separation distance of 1 m (100 cm) from persons within the area. The second antenna is connected via cable that has typical 1~10 dB attenuation (depends on the length of the cable) to the BDA MOBILE port. This type of antenna is omnidirecttional (isotropic), or wide beam, with 0 to 2 dBi typical gain and is installed and distributes indoor (in buildings, tunnels, basements, park lots, shopping centers etc.). Typical specifications: gain: 2 dBi, VSWR: better than 2:1 , Impedance: 50 ohm. For direct connection to the BDA this antenna must be installed to provide a minimum separation distance of 2 m (200 cm) from persons within the area. Less separation is needed if the power from this power is divided into many antennas covering many floors or areas.

No.: 2.1049 Test Performed By: Russell Grant Date of Test: July 16, 2003 Minimum Standard: 22.917(a) Test Results: Complies. There was no degradation in the occupied bandwidth. Measurement Data: See attached graphs. The occupied bandwidth was measured by comparison of input to the output signal. This was done in order to determine if there was any degradation to the output signal due to the amplification through the repeater. Nemko Canada Inc.
