1. Introduction

The CSB.01 cellular booster is a high performance, microprocessor controlled, bi-

directional RF booster for the North American 850 MHz cellular and 1900 MHz PCS

frequency bands. The booster has an automatic gain and oscillation control system

that will automatically adjust the gain and output power if a signal anomaly occurs.

This booster is designed to operate as a direct connect "plug and play" unit for

maximum performance in weak signal coverage areas.

The CSB.01 is equipped with passive bypass technology. This feature allows the

booster to be passively bypassed and become a pass through cable when boosting is

not necessary, during loss of power or when a fault is detected. This is useful in

applications where the booster is mobile, moving in and out of poor signal areas. The

booster will bypass itself when close to cell towers, completely eliminating any

potential for network disrupting noise power caused by too much amplification near a

cell tower. The technology is also extremely useful in fire and security system

installations where a network connection must always be maintained, even with loss

of power.

The CSB.01 has a wide input voltage range of 8.0 to 36.0V allowing for a variety of

power sources. Integrated LED diagnostics alert the user to events such as

initialization, normal operation, increase in gain, decrease in gain, and fault detection.
