First LTE MU mMIMO deployments in 2017, first 5G MU mMIMO deployments in 2019

More frequency bands @ higher frequency will be added, old bands stay, larger SBW @ higher frequency bands

Continuous increase in antenna elements ► lower power per antenna element ► higher level of integration

Pre-5GAdding Higher Frequencies, More Antennas, Smaller PAs

Waveform: LTE type signals

New bands up to 6 GHz, wider channels

Improved utilization of channel (spectral efficiency), with need to overcome adverse propagation characteristicsMIMO → massive MIMOMIMO takes advantage of multipath propagationMore throughput, i.e., more data over the same channel MIMO is already being used as part of 4G (2T, 4T, etc.)Each “TX” will use a single PAThe higher the frequency, the higher the order of MIMO

More antennas also allow for beamformingFocus energy on defined spatial area

RF Components for Pre-5G

Higher frequency bandsSi LDMOS remains the workhorse in current cellular bandsIII-V expansion (GaN and GaAs) at >3.5GHzLarger parasitic impact require higher level of integration needed

Lower transmit power level for mMIMO & small cellsLower supply voltages Smaller PA footprint requirements require higher levels of integration

Continually increasing signal bandwidth

Continued push for higher efficiency PAsDoherty + DPD still best-in-classRe-evaluate linearization options for mMIMO and small cellsContinue research on alternate high η PA technologies
