Applications
5G base stations 5G customer premises equipment (CPE) Point-to-point radio Product Description The PE188200 is an 8-channel beamforming front-end for 5G applications. It is organized as two independently controllable RF chains of four channels supporting four dual-polarity antennas or eight single-polarity antennas. Time division duplex (TDD) mode operation switches po wer amplifier/low noise amplifier (PA/LNA) branches connected to each antenna port. Integrated splitter/ combiners and a phase and amplitude beamformer for each channel complete each chain. All control is performed via a 4-wire serial peripheral in terface (SPI) bus. On-chip memory holds 512 sets of 8- channel beamforming coefficients. These sets may be allocated in any way between RX and Tx. To enable rapid beam steering, each stored value can be selected by a short two-byte Beam Preset command, or individual beamformer coefficients may be written separately by or dinary write register commands. Similarly, on-chip storage is provided for up to 32 state modes, providing control of all amplifiers and switches for each channel. This allows flexible definition of modes such as RX, TX , idle and sleep. The desired state mode is selected by a one-byte Mode Preset command. Mode lookup tables are read from and written to via the SPI bus like ordinary registers. The SPI bus supports pass-through operation to control several chips on the same bus for ease of multi-chip control in large antenna arrays.
