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 CBDA Downlink path receives the RF signals from base station, amplifies them and transmits them to the subscriber. The BDA 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.Two aditional filters , one in uplink path and one in down link path are used to improve isolation. 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 at its output. The step attenuator is used to set the BDA repeater gain. The power amplifiers in the BDA have an AGC option switch. When switched on, the AGC circuit limits the amplifier output power. The AGC circuit senses the output power and introduces more attenuation, when the output power exceeds the preset level. This way the gain of the amplifier is reduced, its output power is limited and the intermodulations products are kept below the desired level. The AGC amplifier has a Power LED lamp that illuminates when the output power has reached the preset power limit. Page 3 of 8 CBDA-PCSAC-10W80 INST-FCC.doc

The RF connector labeled “Base” should be connected to the antenna pointing to the base station; usually a rooftop antenna. The RF connection labeled “Mobile” should be connected to the antenna pointing into the area to be covered by the BDA; such as inside a building. Step Attenuator & RF Gain Setting For proper operation of the BDA; the isolation between the base station antenna and the mobile antenna should exceed the BDA gain by at least 12 dB. If the BDA gain is higher than the isolation between the antennas, oscillation would start and would saturate the amplifier. Isolation of few dB higher than the BDA gain cannot start oscillations but would cause gain ripple in the band. The step attenuator on the low noise amplifier can reduce the BDA gain. By using the rotary knob , the attenuation can be adjusted in 2 dB steps up to 30 dB. Page 4 of 8 CBDA-PCSAC-10W80 INST-FCC.doc

Their amplifier has a directional coupler and a detector at the output of the high power amplifier 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 out the amplifier is within the set limit (when the AGC is On and when the AGC is OFF). The switch on the RF amplifier enables the AGC function. If the AGC is disabled then the amplifier gives maximum gain. Note: The BDA is shipped with the AGC switch in the OFF position. The screw on the amplifier is used to set the AGC power limit. This is a factory-preset level. RF Power LED: The LED illuminates when the output power exceeds the AGC Set . AGC ON / OFF Switch: When OFF the amplifier works with its highest gain (AGC Function OFF). When set to ON (AGC Function ON) the amplifier power output cannot exceed the set limit.

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 16 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 0.5 m (50 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 CBDA 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.). For single indoor antenna, the antenna must be installed to provide a minimum separation distance of 0.5 m (50 cm) from persons within the area. When 4 antennas (or more) are used, the indoor antenna must be installed to provide a minimum separation distance of 0.2 m (20 cm) from persons within the area.
