  • Fundamentals of Electronics: Book 2: Amplifiers: Analysis and Design

    This book, Amplifiers: Analysis and Design, is the second of four books of a larger work, Fundamentals of Electronics. It is comprised of four chapters that describe the fundamentals of amplifier performance. Beginning with a review of two-port analysis, the first chapter introduces the modeling of the response of transistors to AC signals. Basic one-transistor amplifiers are extensively discussed. The next chapter expands the discussion to multiple transistor amplifiers. The coverage of simple amplifiers is concluded with a chapter that examines power amplifiers. This discussion defines the limits of small-signal analysis and explores the realm where these simplifying assumptions are no longer valid and distortion becomes present. The final chapter concludes the book with the first of two chapters in Fundamental of Electronics on the significant topic of feedback amplifiers. Fundamentals of Electronics has been designed primarily for use in an upper division course in electronics for electrical engineering students. Typically such a course spans a full academic years consisting of two semesters or three quarters. As such, Amplifiers: Analysis and Design, and two other books, Electronic Devices and Circuit Applications, and Active Filters and Amplifier Frequency Response, form an appropriate body of material for such a course. Secondary applications include the use with Electronic Devices and Circuit Applications in a one- semester electronics course for engineers or as a reference for practicing engineers.

  • Design of broadband GaN doherty power amplifiers

    This paper presents a modified Doherty power amplifier (DPA) architecture to release bandwidth limitation of the conventional DPA. The proposed DPA structure eliminates two quarter wavelength impedance inverters used in the conventional DPAs (one is after the output matching network of the carrier amplifier and the other one is before the load of the DPA). Instead, both the carrier and peak amplifiers in the proposed DPA are matched to 70 Ω (1.4*Z0) at the output ports, which enables the easy implementation of broadband matching networks. Broadband input and output matching networks are then designed to achieve wideband Doherty power amplifiers with enhanced performance. To verify the design concept, a broadband microstrip DPA is designed, fabricated, and measured on a Duroid 5880 substrate with 2.2 dielectric constant and 0.787 mm substrate thickness. In the working frequency band (0.8 to 1.2 GHz), the designed DPA provides 50.8% to 78.5% power-added efficiency (PAE) at full output power, 30.3% to 40.1% PAE at 6 dB of output power back-off (OBO), 10.8 to 14.8 dB gain (the gain variation is within 2.6 dB over different input power levels at each specific frequency), and maximum output power between 40.2 and 42.9 dBm.

  • Lossless feedback amplifier design

    Lossless feedback can be applied to three types of microwave amplifiers: (1) high gain amplifiers (HGA) Mason 1954 (2) low noise amplifiers (LNA) Vendelin 1975 and (3) high power amplifiers (HPA). The LNA and HPA are duals of each other. This paper gives a tutorial review of all three feedback amplifiers.

  • Effect of maximum power supply voltage on envelope tracking power amplifiers using GaN HEMTs

    This work discusses wideband high efficiency envelope tracking (ET) power amplifiers using GaN high electron mobility transistors (HEMTs) to achieve high gain and high efficiency with good linearity. The performances of two ET amplifiers using the same GaN RF device and envelope voltages of 30-V peak and 45-V peak are compared experimentally. With the higher dynamic voltage swing (45-V case), a considerably higher PAE was obtained, as well as a higher gain. For a WCDMA signal with 7.7 dB peak-to-average ratio (PAR) and 3.84 MHz bandwidth, the 45-V peak envelope tracking amplifier shows an overall drain efficiency above 50 % at an average output power above 30 W and a gain of 13.7 dB. The result was achieved with a normalized RMS power error below 3 % and an ACPR1 of -45.2 dBc using memory-less digital predistortion. By comparison, the PAE achieved with the 30-V peak envelope tracking amplifier was 45 %, and the gain was 10.8 dB, with a similar linearity performance. The improved results can be understood on the basis of loss minimization from device on-resistance.

  • The design of highly linear broadband power amplifiers

    The use of the feedforward technique to linearise high-power amplifiers is described, with particular reference to its use in cellular radio base station applications. The feedforward technique is, however, applicable to a wide variety of applications requiring high degrees of linearity and broad bandwidth operation. Measurements on a practical system are presented to illustrate the exceptional levels of performance which can be achieved with this kind of system.<<ETX>>

  • Sensitivity and mitigation of Reverse IMD in power amplifiers

    The generation of intermodulation distortion products due to the coupling of signals into the output port of an amplifier, often referred to as Reverse Intermodulation Distortion (IMD) can be a major problem when multiple transmitters are operated in close proximity. Such conditions can exist at cell telephone sites, broadcast facilities and even on satellites. This type of distortion can also be a problem when making high linearity measurements. The sensitivity of different types of power amplifiers to Reverse IMD and techniques for mitigating the resulting distortion has been experimentally investigated.

  • Demonstration of 16/spl times/10 Gb/s WDM transmissions over 5/spl times/80 km using distributed Raman amplifiers and gain clamped semiconductor amplifiers as inline amplifiers
