Power Amplifiers for Communications

Peak E ciency Power Added E ciency (PAE) is a popular metric. P out is the output power, P in is the input power, and P dc is the DC power consumption of the PA For high power gain systems (G p), the e ciency approaches the drain drain e ciency ( d), or for a BJT, the \collector" e ciency, or simply the e ciency of the last stage

EECS 242: Mixer Noise and Design

The mixer voltage gain is the ratio of the output voltage signal at the IF frequency to the RF input voltage signal. If the LO is at either peak, one

Lecture 12: Noise in Communication Systems

The noise of the first stage is the most important. Thus, every communication system employs a low noise amplifier (LNA) at the front to relax the noise requirements A typical LNA might have a G = 20dB of gain and a noise figure NF < 1.5dB. …

Lecture 15: Introduction to Mixers

Image Reject Filter In our example, RF = 1000MHz, and IF = 1MHz.The Imagine is on 2IF = 2MHz away. Let’s design a filter with f0 = 1000MHz and f1 = 1001MHz. A fifth-order Chebyshev filter with 0.2dB ripple is down about 80dB at the IF frequency. But the Q for such a filter is Q = 103MHz 1MHz = 103 Such a filter requires components with Q > 103! A. M.

Nonlinear System Theory

phase-plane analysis describes nonlinear phenomena such as limit cycles and multiple equilibria of second-order systems in an efficient manner. The theory of differential equations has led to a highly developed stability theory for some classes of nonlinear systems. (Though, of course, an engineer cannot live by stability alone.) Functional
