Low-noise microwave transistors and amplifiers
Abstract
Subjects related to noise characterization and measurements are considered, taking into account noise figures of radio receivers, the theory of noisy fourpoles, the effect of feedback on the noise figure, the wave representation of amplifier noise, a wave approach to the noise properties of linear microwave devices, and the measurement of losses in noise-matching networks. The noise properties of bipolar transistors are examined along with the noise properties of field-effect transistors. Other topics explored are related to low-noise amplifier design. A scattering parameter approach to the design of narrow-band amplifiers employing conditionally stable active elements is described, and an introduction to simulation and optimization is provided. Practical amplifier techniques are also discussed, giving attention to a wide-band low noise L-band balanced transistor amplifier, and an integrated 4-GHz balanced transistor amplifier.
