Abstract: In cellular telephony, a plurality of communication signals which are received at a base station for wireless transmission are multiplexed onto a single physical medium which runs up a mast. This reduces the use of cabling running up the mast with an attendant savings in cost.

Abstract: Methods and apparatus are provided for efficiently coupling singly terminated networks with doubly terminated networks. An isolation network is disposed between a singly terminated network and a doubly terminated network. The isolation network is a three terminal device having an input terminal connected to the output of the singly terminated network and having an output terminal connected to the input of the doubly terminated network. An isolation terminal is provided that receives and dissipates energy reflected from the input of the doubly terminated network, such that substantially no energy is received or seen by the output of the singly terminated network.

Abstract: Methods and apparatus are provided for efficiently combining and filtering a plurality of input signals into a single combined output signal. M number of input signals are received, combined and filtered by a filter/combiner. The filter/combiner has a plurality of input stages for each input signal, and an output stage that combines the outputs of the input stages into the combined signal. The filter/combiner has a desired overall filter transfer function designed to filter signals having frequencies outside a passband and which passes the desired M input signals.

Abstract: Methods and apparatus are provided for efficiently amplifying a signal. An input signal is decomposed into a plurality of two state signals, each two state signal having a respective on level and off level. This may involve sigma-delta modulation and phase splitting. Each of the two state signals is amplified with a respective switching power amplifier to produce a respective amplified signal. The amplified signals are combined to produce an amplified version of the input signal.
