Frenzel, Communications Editor Transmitter power amplifiers (PAs) consume more power than any other circuit in today's wireless applications. In some cases, PAs swallow up more than 50% of the power budget. Also, their inefficiency produces excessive wasted power as heat. With cellular basestations joining the green trend and cell phones including ever more features and multiple radios that shorten battery life, the industry is turning its attention to the PA. Fortunately, many products are now available to plug this power drain.

Most function generators and network analyzers have one port to provide the output signal. If a differential signal is needed, then you may need to acquire a network analyzer with two output ports at great cost. Of course, there are alternate solutions in generating a differential signal without acquiring expensive equipment. The two most popular solutions include the use of a transformer or a power splitter.
