In very recent years, the revolution in digital signal processing technologies has been applied to SSB receivers and transmitters to produce levels of performance and flexibility (programmability) that are setting new standards in radio design. Also, developments in high-power, solid-state transistors and circuit design has revolutionized linear power amplifier (LPA) design. The development of ultralinear power amplifiers using feedforward techniques promises to reduce transmitter distortion products by two or three orders of magnitude. Improvements in high-power, fast-tuning vacuum tube amplifiers are described in this book. Advanced measurement techniques for high-performance receivers and transmitters have been developed.
