Designing with the MGA-72543 RFIC Amplifier / Bypass Switch
ثبت نشده
چکیده
The purpose of the switch feature is to prevent distortion of high signal levels in receiver applications by bypassing the amplifier altogether. The bypass switch can be thought of as a 1-bit digital AGC circuit that not only prevents distortion by bypassing the MGA-72543 amplifier, but also Figure 1. MGA-72543 Functional diagram. reduces front-end system gain by approximately 16 dB to avoid overdriving subsequent stages in the receiver such as the mixer.

Comparison of Three Preamplifier Technologies: Variation of Input Impedance and Noise Figure With B0 Field Strength
Introduction Array coil preamplifiers are subjected to large magnetic fields since they are placed close to each coil to minimize SNR losses due to cabling. Noise figure (NF) and input impedance are key parameters that must vary minimally with magnetic field strength and orientation [1,2] to ensure there are no differences in performance between the bench and the bore. In this work we compare t...
متن کاملA Class E Power Amplifier with Low Voltage Stress
A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
