The limitation of the BTS has traditionally been its sensitivity to the Uplink, or received signal at the BTS. The antenna receives the signal from the mobile, but this can be degraded by the feeder cable losses from the antenna down the mast to the BTS. The Airtech Masthead Amplifier employs a low noise amplifier to transmit the improved signal strength down to the BTS overcoming the signal degradation due to the feeder cable losses. The result is a greater sensitivity of the receive system, providing better quality, greater coverage and generally fewer dropped calls, as well as reducing the power required by the mobile phone from any particular location which may increase the battery life and general user satisfaction with the network. The Airtech Booster is designed to increase the downlink signal level by placing the high power amplifiers at the masthead reducing the feeder losses. This extends the range of the base station further, reducing infrastructure costs or improving coverage in black spots. CAUTION: PRIOR TO WORKING ON OR INSTALLING THE BOOSTER SYSTEM OR ANY OF ITS COMPONENTS, ENSURE THAT THE BTS TRANSMITTER RF OUTPUT IS TURNED OFF AND THAT PRECAUTIONS ARE TAKEN TO ENSURE THAT THE TRANSMITTER CANNOT BE ACTIVATED DURING THE EQUIPMENT INSTALLATION. THERE ARE NO USER SERVICABLE COMPONENTS INSIDE THE BOOSTER. RETURN THE UNIT TO THE FACTORY IF SERVICE OR REPAIR IS REQUIRED.

GENERAL 1.1System The Masthead Booster System consists of the following: • The Masthead Bi-directional Amplifier or Booster (MHB) including filters, LNA and HPA • The Power Distribution Unit (PDU) to supply DC to MHB and provide system alarms Technical Descriptions of the Mast Head Booster, Power Distribution Unit, Bias Tee and other ancillary equipment is given in this document. The system enables dual duplex operation. The DC Power of the booster (MHB) is supplied via the BTS antenna coaxial feeder cable using Bias Tees. The Mast Head Booster described in this documents is used at the tower top to provide increase in the coverage of the Cellular BTS. This is achieved by providing up to 12dB gain in the Transmitter Path (downlink) and up to 22dB gain in the Receiver Path (uplink). Receive Path The purpose of the low Noise Figure Amplifier in the receive path installed at the tower top close to the antenna is to compensate for all the losses between the antenna and the front end of the BTS receiver and thus improve the BTS sensitivity. The gain of the LNA is remotely adjustable from the PDU via a serial communication interface injected on to the feeder cable through the Bias Tee. G\Dev\Ranjit\Booster\Booster_Description COMMERCIAL IN CONFIDENCE 06/08/01 Page 4 of 29 Transmit Path REMEC-Airtech’s High Power Booster is installed at the tower top to provide a maximum of +43 dBm (20 W) output power at the antenna port thus overcoming any feeder cable losses. The REMEC-Airtech Booster provides up to 12 dB of gain thus allowing very low incoming signals (down to +31 dBm) to provide +43 dBm (20 W) at the antenna input. The gain of the HPA in the MHB is remotely adjustable from the PDU via serial communication interface injected on the feeder cable through the Bias Tee. 2. SYSTEM DESCRIPTION 2.1GENERAL The Booster System is used to compensate for cable loss between the BTS and the antenna and provide extra power on the Transmitter path.

Digital Modulation Techniques The Booster provides 12.0 dB of gain to all signals generated by a GSM PCS Base Station. The Base Station generates a digitally modulated signal using a GMSK modulation type. This signal is input into the Booster and then amplified up to a maximum of 20 Watts (+43.0 dBm).

Procedure for Setting Transmitter Power The HPA attenuator switch sets the transmit gain. The gain will be a maximum 12.0 dB at the “ 0” switch setting. The switches cover an attenuation range of 16.0 dB ( 0 to F in hexadecimal) in 1.0 dB steps. The LNA attenuator sets the receive gain in the booster. The gain will be a maximum of 22.0 dB at the “0” switch setting. The switches cover an attenuation range of 16.0 dB ( 0 to F in hexadecimal) in 1.0 dB steps. The transmit amplifier provides a maximum RF output power of 20 Watts ( +43.0 dBm) and a nominal maximum gain of 12 dB. It is essential that the gain of the booster is adjusted to ensure that the output power does not exceed this level. The following procedure shall be followed: 1. Set the booster transmit attenuation to 16.0 dB by setting the rotary switch on the control panel to F. 2. Enable the BTS Tx carrier output at the required operating power level. 3. While monitoring the booster output power using a suitable power meter, gradually decrease the Tx attenuation until the booster output power reaches the required level (not exceeding 20 W). The booster system is now ready for performance testing.

The system consists of a high power amplifier and a bandpass filter in the transmit path and bandpass / lowpass filters and a Low Noise Amplifier in the receive path. The system shall be designed to deliver single carrier Tx nominal gain of 12 dB with a maximum output of +43 dBm (20 W). The nominal gain of Rx shall be 22 dB. The system shall be housed in a compact low volume, lightweight IP68 enclosure. This product is designed to extend coverage, increase traffic and improve the quality of the signal within a network cell. The unit shall be convection cooled. Figure 1 shows a block diagram of a Single Feed Single Antenna (SF-SA) PCS 1900 Booster. This system is connected to the BTS via a common cable for receive and transmit signals, and to a common transmit / receive antenna. As an option, the Booster shall provide a by-pass of the HPA in the transmit section as shown on figure 2, which shall be enabled if the HPA fails. By-pass of the LNA in the receive section shall be a standard configuration, which shall be enabled if the LNA fails The Booster shall be designed to operate over the entire PCS band, but the filters optimized to pass only a 15 MHz band (e.g. A, B, C band). The unit shall be designed to mount on a mast (pole) or a wall and integrated with a customer provided sector antenna. A Solar Shield shall be included to provide protection against direct Sun Radiation. A low pass filter and a variable attenuator at the output of the Low Noise Amplifier shall form an integral part of the LNA tile. The functional status of the LNA shall be monitored, e.g. current drawn by the LNA, and a low loss bypass switch shall be incorporated to provide failure mode operation. An isolator, a VSWR monitoring circuit at the output and a variable attenuator at the input shall form an integral part of the HPA tile. Couplers at the input and the output of the HPA shall be used to monitor the input signal level and the level of the reflected signal at the output port. The Booster shall be designed to ensure good thermal stability. The Booster unit shall also include voltage regulators to provide the required voltage to the amplifiers and to account for any voltage drop across the feeder cables which transmit DC power from the Power Distribution Unit (PDU) at the BTS to the Booster unit. The DC power shall be transmitted via the RF feeder cable using Bias Tees to couple the DC power onto the RF cables. The Bias Tees shall also provide protection against a lightning strike. A serial data interface shall be used to monitor the status of the amplifiers, and display on the PDU at the base. The data interface system may also be used to transmit commands from the BTS to adjust the variable attenuators within the Booster Unit. The serial data signals shall be coupled onto the RF feeder cable via the Bias Tees used for coupling the DC power. The Booster unit shall have 7/16 RF connectors for the antenna and the RF feeder cable …

The RF goes in on J1 at a power level of +21.0 dBm it is then amplified by transistor 1 by 8.0 dB approximately. The RF is then routed to transistor 2 and is further amplified by 8.0 dB. The output of amplifier 2 is then equally divided by a hybrid splitter. Each half is then amplified by 7.0 dB by transistor amplifier 3 and 4. Both RF signals are then combined by a hybrid coupler to produce a nominal power of + 44.0 dBm. A sample of RF is provided on J2 ( NOT USED ON REMEC-Airtech Product). There is a forward power detector, which converts a sample of RF to a video voltage which is then routed to the booster control circuitry. There is also an isolator on the output of the HPA which allows RF to pass in and out while providing isolation by dissipating any reflected RF power. The reverse power detector detects reflected power and once again converts it into a video voltage that is then fed to the booster control circuitry. The Bias current enables switches on transistors 1, 2, 3 and 4 allows for correct RF operation and amplification. The RF is provided through SMB J3.
