Rev 2.02 E7B15 The effect of intermodulation products in a linear power amplifier is the transmission of spurious signals. E7B16 Third-order intermodulation distortion products are of particular concern in linear power amplifiers because they are relatively close in frequency to the desired signal. E7B17 A grounded-grid amplifier has low input impedance. E7B18 A klystron is a VHF, UHF, or microwave vacuum tube that uses velocity modulation. E7B19 A parametric amplifier is a low-noise VHF or UHF amplifier relying on varying reactance for amplification. E7B20 Generally a FET is best suited for UHF or microwave power amplifier applications.

Rev 2.02 E7C01 In a low-pass filter Pi-network the circuit consists of a capacitor in parallel with the input, another capacitor is in parallel with the output, and an inductor is in series between the two and between the network's input and output. E7C02 A T-network with series capacitors and a parallel (shunt) inductor transforms impedance and is a high-pass filter. E7C03 The advantage of a Pi-L-network over a Pi-network for impedance matching between the final amplifier of a vacuum-tube type transmitter and an antenna is greater harmonic suppression. E7C04 A network can transform complex impedance to resistive impedance by canceling the reactive part of an impedance and transforms the resistive part to the desired value. E7C05 A Chebyshev filter type is described as having ripple in the passband and a sharp cutoff. E7C06 The distinguishing features of an elliptical filter is extremely sharp cutoff, with one or more infinitely deep notches in the stop band Jack Tiley <strong>AD7FO</strong> Page 69 3/15/2009
