Abstract:

This article presents K/Ka-band four-element four-beam phased-array transmitter (TX) and receiver (RX) front-ends. Hybrid-packaged technology is employed, consisting of one TX/RX 65-nm CMOS beamformer and four 0.1- $mu$ m GaAs power amplifiers (PAs)/low-noise amplifiers (LNAs). Each beam maintains a full connection to every antenna element without degrading …

Abstract:

A digital-to-analog converter (DAC)-based polar transmitter (TX) is proposed for multicarrier signaling in wireline applications. The proposed TX achieves a 50-Gb/s total data rate with maximized spectral efficiency by using three parallel 5-GS/s DAC-based drivers and two orthogonal carriers of 5 and 10 GHz. The three DAC-based drivers operating …
