In any active wireless system, a signal will be generated and transmitted through an antenna. The signal’s generating system is called a transmitter. The specications for a transmitter depend on the applications. For long-distance transmission, high power and low noise are important. For space or battery operating systems, high efciency is essential. For communication systems, low noise and good stability are required. A transmitter can be combined with a receiver to form a transceiver. In this case, a duple……
