Mini 30mW User’s Manual 1. Overview Mini 30 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 30 designed to improve coverage for wireless products within a facility.
Mini 30mW User’s Manual 2 Repeater Design The Mini 30 is housed in an aluminum chassis that is waterproof for indoor use. The chassis has a design suited for indoor use. The Mini 30 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. This amplifier board is different types depending on the supported system.
