Lecture 9: Intercept Point, Gain Compression and Blocking
Finally, equating the cubic terms we have 0 = a1b3 +a22b1b2 +a3b 3 1 b3 = 2a2 2 a5 1 − a3 a4 1 It’s interesting to note that if one power series does not have cubic, a3 ≡ 0, the inverse series has cubic due to the first term above.

Power Amplifiers for Communications
rfic.eecs.berkeley.eduPeak 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

Lecture 12: Noise in Communication Systems
rfic.eecs.berkeley.eduThe 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. …

Nonlinear System Theory
rfic.eecs.berkeley.eduphase-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
