The Model 110 Miniature In-Building Amplifier (Mini- IBA) was developed by Cellular Specialties, Inc. (CSI) to enhance cellular performance within these enclosed structures. Specifically, the Mini-IBA is designed to cover small areas such as home offices, small workshops, etc. -
Page 4: Circuit Description
Circuit Description Uplink The uplink rf circuit consists of two stages of gain. Each gain stage is a monolithic integrated circuit (mmic) mounted to a printed circuit board (PCB). The signal received by the inside antenna is directed to the 1 mmic stage by a frequency diplexer, which separates the uplink frequency (806- 824 MHz) from the downlink frequency (851-869MHz). -

Contents The unit package contains the following: Model 110 Mini-IBA Power Transformer, 110 volt to 12 volt – model number ( User Manual Optional Accessories Accessories are available directly from Cellular Specialties, Inc. or any of CSI’s distributors. - Page 8 If coordinates are not available, measure the RSSI at the outside antenna output by connecting a phone to the outside antenna and slowly rotating the antenna until a maximum reading is obtained. The Mini-IBA and inside antenna should be centrally located, keeping coaxial cable runs to a minimum.
- Page 9 Safety Precautions CAUTION ! ! ! ! For INDOOR use, an Omni-Directional Antenna with a maximum gain of 3dBi is authorized for use with this unit. Inside antennas must be positioned to observe minimum separation of 20 cm. (~ 8 in.) from all users and bystanders. For the protection of personnel working in the vicinity of inside (downlink) antennas, the following guidelines for minimum distances between the human body and the antenna must be observed.
