MR-BDA60-X INSTALATION AND OPERATINAL MANUAL 25/03/05 TABLE OF CONTENTS GENERAL INFORMATION GENERAL DESCRIPTION BLOCK DIAGRAM COMPOSITION INSTALLATION ELECTRICAL SPECIFICATION MECHANICAL PERFORMANCE ENVIRONMENTAL Description and Operational Manual of MR-BDA60-X General Information The MR-BDA60-X Bi-Directional Amplifier is designed to enhance radio communication in buildings, basements, parking garage and other RF shielded environments. An MR-BDA60-X system includes all the materials necessary to provide clear, continuous donor site extension coverage within a building or other shadowed location. MR-BDA60-X is suitable for CDMA/TDMA/N-AMPS systems. The small size and flexibility of the MR-BDA60-X system makes it suitable to introduce service to: Shielded buildings (offices, shopping malls, hospitals, airports and underground parking garages or other. General Description MR-BDA60-X Bi-Directional Amplifier is based on a duplexed two path configuration. It features sharp out-of-band attenuation for better selectivity and improved isolation between the receiving and transmitting paths. Passband insertion losses at transmitting path are very low, thus minimizing RF power losses. An MR-BDA60-X system example is show below. Using an external roof or vertical wall-mounted antenna, downlink signals from a donor base station site are received and directed via cable and diplexer to the low noise amplifier (LNA). Low noise amplifier provides gain to set the system noise figure. The next pre-amplifier (Pre-Amp.) provides sufficient signal strength and frequency characteristics to the power amplifier (PA). Power amplifier with highly linear characteristics improves overall system linearity. The signal transmission from the portable back to the donor follows the same principles. Since these amplifiers are Bi-Directional, the uplink signal is amplified in its own amplifier path and routed to the external antenna and back to the donor site. Voltage variable attenuators, couplers in each path and control system provide manual gain control of each channel. The DC system current consumption and abnormal operation in each path are monitored by means of LED indicators. The MR-BDA60-X Bi-Directional Amplifier is a low-power, high-gain device. A compact, lightweight, weatherproof box will mounting, assures easy and reliable installation.

Green LED “ON” is light when DC power from external power supply +12V or from RF connector “MOBILE” is on. Two red LEDs “OVERLOAD” are indicators of abnormal operation in each channel. LED “DOWN” is on when input signal of channel “MOBILE” (Up Link) is big and the channel in position 1 dB compression. LED “UP” is on when input signal of channel “SITE” (Down Link) is big and the channel in position 1 dB compression. On the rear panel are placed RF connector “SITE (DC IN)” for connection with Down Link part of antenna and DC connector “12V” for connection with external power supply +12VDC. On the higher side of MR-BDA60-X are placed two holes for manual control of gain in each channel. Gain manual controls are provided with potentiometers in each channel of MR-BDA60-X. Potentiometer “DOWN” provides manual gain control in Up Link. Potentiometer “UP” provides gain control in Down Link. Installation 1. Install MR-BDA60-B1 on the place and support the casing with four screws through four mounting holes. 2. Check the isolation between the donor antenna and mobile antenna. 3. Connect RF cable with RF connector “MOBILE” of MR-BDA60-B1 and Mobile part of antenna. 4. Connect RF cable with connector “SITE (DC IN)” of MR-BDA60-B1 and Base part of antenna. 5.

Page 2 of 2 Appendix E MFE Evaluation FCC 1.1310 states the criteria listed in the table below shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in Sec. 1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of Sec. 2.1093 of this chapter. Further information on evaluating compliance with these limits can be found in the FCC's OST/OET Bulletin Number 65, ``Evaluating Compliance with FCC-Specified Guidelines for Human Exposure to Radiofrequency Radiation.'' Frequency Range (MHZ) Electric Field Strength (V/m) Magnetic Field Strength (A/M) Power Density (mW/cm 2 ) Average Time (A) Limits for Occupational/Control Exposures 300-1500 -- -- F/300 6 1500-100,000 -- -- 5 6 (B) Limits for General Population/Uncontrolled Exposures 300-1500 -- -- F/1500 6 1500-100,000 -- -- 1 30 9.1 Fries Formula Fries transmission formula: Pd = (P out *G)/(4* p*r 2 ) Where Pd = power density in mW/cm 2 P out = output power to antenna in mW. G = gain of antenna in the direction of interest relative to an isotropic radiator. R = the distance between the observation point and the center of the radiator in cm. Pd is the limit of MPE, 1mW/cm 2 . If we know the maximum gain of the antenna and the total power input to the antenna we can calculate the distance r where the MPE limit is reached. 9.2 EUT Operating Condition The maximum output power of the EUT is 26 dBm as tested and specified by the manufacturer. An antenna gain of 6 dBi is assumed. 9.3 RF exposure evaluation distance calculation Freq (MHz) Output Power to Antenna (dBm) Output Power to Antenna (mW) Antenna Gain (dBi) r (cm) 824 23 200 6 5 894 26 400 6 7 As shown above, the minimum distance where the MPE limit is reached is 7 cm for this EUT
