RF Power Amplifiers for 5G
Higher frequency bands
?Nearly all 4G radios operate below 3GHz
?
LTE Advanced may drive systems up to 6 GHz (2X)
?5G will expand highest bandwidth systems beyond 60 GHz (20X) ?
Varying global spectrum allocations require vendors to create systems across full frequency range
Lower transmit power for mMIMO & small cells
?40 – 80W PA’s are industry standard for FDD LTE ?
10 – 20W PA’s are industry standard for TDD LTE ?mMIMO concept is driving PA power / antenna down dramatically for LTE Advanced (1 – 5W)
?5G systems will see even more antennas / BTS and lower power / antenna
Required expansion of scope Current Focus of RF PA Vendors
