  • Smartphones of today need to support numerous frequency bands in the sub 6 GHz (or sub 7 GHz) frequency range including carrier aggregation requirements for aggregation of two or more system bandwidths/bandwidth parts (in different frequency bands or in the same frequency band). Since other requirements, such as requirements of at least 2 receiver antennas (as in e.g., Long-Term Evolution, LTE) and sometimes 4 receiver antennas (e.g., for some frequency bands in New Radio, NR) need to be fulfilled as well, the transceiver architecture will become quite complex.
  • LTE Long-Term Evolution
  • NR New Radio
  • a solution to handle the frequency band complexity in sub 6 GHz (or in sub 7 GHz) is an architecture with a common transceiver, comprising analog baseband (BB) filters and BB amplifiers, e.g., variable gain amplifiers (VGAs), local oscillators (LO), phase locked loops (PLLs), mixers, up converters, down converters, and possible low noise amplifiers (LNAs), for all sub 6 GHz (or sub 7 GHz) frequency bands.

  • mmW millimeter wave
  • 5G-NR increases the capacity of the cellular system (e.g., by off-loading devices to mmW from the sub 6 GHz spectrum) and enables higher transmission rates, e.g., transmission rates of Gb/s.
  • analog beamforming In order to mitigate the higher path loss in mmW, a higher number of antennas is needed to beamform the signal. Typically, analog beamforming is used. In analog beamforming (BF) the signal from each antenna is combined in the analog domain using phase shifters.
  • a number (typically 2-4) of antenna panels are needed in the mobile phone.
  • logic circuits in the mobile phone will need to be able to switch between the different antenna panels and utilize an antenna panel that is not blocked (e.g., in order to transmit/receive a radio signal with higher or sufficient quality).
  • the state-of-the-art solution of adding mmW transceivers is by down converting the mmW radio signal to a sub 6 GHz signal, at the receiving side, and then feed the down converted signal to a sub 6 GHz transceiver (and up converting a sub 6 GHz signal from the sub 6 GHz transceiver to a mmW radio signal for transmission).
  • the mmW front ends will not only comprise PAs, LNAs and band filters, but also mixers, up converters, and downconverters, converting the mmW signal to an intermediate frequency (IF) signal.

  • control information needs to be sent over the interface and hence an increased number of information signals/streams increases the need for I/O pins as well as the need for more ADCs/DACs, thus enlarging a chip/printed circuit board (PCB), comprising the BB processor, and increasing the cost of the chip/PCB/BB processor.
  • PCB chip/printed circuit board
