NOKIA TBU Unit Description 1. INTRODUCTION The Nokia Transmitter Booster Unit (TBU) is the core of the Nokia Booster configuration. The Booster configuration fits seamlessly into Nokia's 3rd Generation base stations, enabling the same geographic coverage with fewer base stations. The main units comprising the Booster configuration are: Transmitter Booster Unit (TBU) Antenna Filter High-power Unit (AFH) Masthead Amplifier (MHA) The TBU provides amplification for down link (transmitted RF).
TBU Unit Description NOKIA 2. GENERAL DESCRIPTION 2.1. Features Following arc the main features of the TBU: * 7dB amplification for 65 W output power for down link (transmitted RF) Continuous self-testing for gain, temperature and output SWERVE ¢ Internally controlled cooling fans * Input overload protection. 2.2. Operation The TBU amplifies the input signal from the TRX and outputs the amplified signal to the AFH unit.
