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. Combined with interior ceiling mounted low profile antennas, and an exterior mounted
Yagi or Patch Antenna, the Mini 30 boosts the signal level for distribution within the interior areas,
reducing the problem of dropped calls and signal fades. The Mini 30 can also be used in mobile
applications, improving voice quality and range in areas of poor coverage.
Figure 2.1 Fundamental configuration of Mini 30
All of our packages are engineered using only FCC approved amplified components. They are
designed not to disrupt local wireless communication but to add service to areas that otherwise would
not have the coverage that the customer requires. All of Mini 30 is easily installed.

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.
The followings are the Technical Specification of Mini 30.

Figure 4.1 Block Diagram of Band Selective Repeater
Figure 4.1 shows a block diagram of a band selective repeater. This diagram is applicable to
repeaters for CDMA systems.
4.1 Downlink signal path
The downlink signal path, i.e. from the base station through the repeater to the mobile station, is
described for Mini 30 in the above block diagrams.
4.2 Uplink signal path
The uplink signal path, i.e. from the mobile station through the repeater to the base station, is identical
to the downlink path but the other way round. Only some levels and component values differ.
