Mini 200mW User’s Manual 1. Overview Mini 200 will bring in those weak cellular phone signals reducing dropped calls and allowing you to use cell phones ...even deep inside a building. At the heart of all of our systems is a Mini 200 designed to improve coverage for wireless products within a facility.
Mini 200mW User’s Manual 2. Repeater Design The Mini 200 is housed in an aluminum chassis that is waterproof for indoor use. The chassis has a design suited for indoor use. The Mini 200 has several RF amplifiers and components on a board with an aluminum body. Furthermore, the RF components are implemented within RF CMOS IC or MMIC technologies. A board that contains several RF amplifiers and components is shielded under a metal cover.

Mini 200mW User’s Manual 3. Repeater Configurations The Mini 200 consists largely of a body and an antenna. The body of the Mini 200 has an RF unit, a main control unit and a power supply unit. Specifically, the antenna unit is separated as a donor antenna and distribution antenna. 3.1 Body The following is the picture of the body of Mini 200. Figure 3.1 A body of the Mini 200 R-Tron., Inc.
Mini 200mW User’s Manual 3.1.1 RF Unit The RF Unit significantly functions an RF amplifier to amplify the weaken transmitted signal from a base station. Figure 3.2 An RF Unit of the Mini 200. R-Tron., Inc.
Mini 200mW User’s Manual 3.1.2 Main Control Unit (MCU) The ARCU board is the control unit of the repeater. The ARCU board is used to supervise and control operational parameters such as gain control, ALC handling, etc. The ARCU takes care of alarms and the event log, password and logon, and many other procedures. Figure 3.3 A Main control unit of the Mini 200. 3.1.3 Power Supply Unit (PSU) The Power Supply Unit (PSU) roles in each needed dc power source as well as converter of ac power to dc power.
Mini 200mW User’s Manual 3.2 Antenna Unit The Mini 200 has two antennas, a donor antenna and a distribution antenna, to provide a good communication service. 3.2.1 Donor Antenna (Yagi Antenna) A donor antenna is used for receiving the transmitted signal from a base station.
