Abstract :
In this paper the design and realization of the filtering units included into a Master Head Amplifier (MHA) for base stations (BTS) is discussed. This device allows to improve the overall noise figure of the BTS transceiver by connecting the low noise amplifier at the antenna output, so eliminating the contribute of noise produced by the feeding cable. The task of the filtering units is to separate/recombine TX and RX paths at the antenna port, allowing the use of a single antenna by the transceiver.
