28-GHz front end module anticipates 5G comms needs
Plextek RFI (Saffron Walden, UK) has prepared a white paper that describes the development of a practical design for an RF building block that will be required for 5G wireless data services.

With the roll-out of 5G expected in the very near future, the research activities of the industry’s key players are now well under way, Plextek says, and have reached the point where custom mm-wave components are being specified, designed and evaluated. The Front End Module (FEM) is an essential component required to enable future mm-wave 5G systems, providing the final stages of amplification in a transmitter and the earliest stages of amplification in a receiver in time division duplex (TDD) systems.

This case study describes the design and evaluation of an SMT packaged FEM MMIC for the 28GHz 5G band (27.5 – 28.35GHz), developed by Plextek RFI and fabricated on WIN Semiconductor’s 0.15 μm enhancement mode GaAs P-HEMT process The device is conveniently housed in a compact, low-cost 5mm x 5mm plastic overmoulded SMT compatible QFN package.
