Perform RF cascade analyses and architectural trade studies covering gain, noise figure, sensitivity, linearity, P1dB, IP3, dynamic range, EIRP, efficiency, stability, spurious performance, and link margin, including simultaneous transmit-and-receive architectures using frequency-division duplexing. Design transmit and receive chains using power amplifiers, low-noise amplifiers, filters, duplexers, switches, couplers, attenuators, mixers, synthesizers, transceivers, phase shifters, beamformer devices, and RF matching networks.
