Abstract
Millimeter-wave wireless networks of the new fifth generation (5G) have become a primary focus in the development of the information and telecommunication industries. It is expected that 5G wireless networks will increase the data rates and reduce network latencies by an order of magnitude, which will create new telecommunication services for all sectors of the economy. New electronic components such as 28 GHz (27.5 to 28.35 GHz) single-chip transmit radio frequency (RF) front-end monolithic microwave integrated circuits (MMICs) will be required for the performance and power consumption of millimeter-wave (mm-wave) 5G communication systems. This component includes a 6-bit digital phase shifter, a driver amplifier and a power amplifier. The output power P3dB and power-added efficiency (PAE) are 29 dBm and 19.2% at 28 GHz. The phase shifter root-mean-square (RMS) phase and gain errors are 3° and 0.6 dB at 28 GHz. The chip dimensions are 4.35 × 4.40 mm.
Highlights
The population of our planet is gradually increasing and has already exceeded 7 billion people.The information needs of the population are growing; at the same time, new technologies such as the Internet of Things (IoT), intelligent transport systems (such as Vehicular Ad hoc Network (VANETs))and virtual and augmented reality are actively developing [1]
power-added efficiency (PAE) at P1dB at Millimeter-wave wireless networks have attracted the most interest as 5G communication systems of the new generation (5G)
The 27.5 to 28.35 GHz band was licensed for 5G wireless networks by the Federal Communications Commission (FCC)
Summary
The population of our planet is gradually increasing and has already exceeded 7 billion people. The growth of data traffic and device connections will require data rates to increase by more than an order of magnitude [2] Responding to these requests, the International Telecommunication Union (ITU) decided to develop a new generation of 5G wireless communications with high transmission speeds (>10 Gbit/s) and ultralow response times (
