Transmit/Receive Dual Polarization Beamformer (SOI) (37.0 GHz to 43.5 GHz): ADMV4928


The ADMV4928 is a silicon on insulator (SOI), 37.0 GHz to 43.5 GHz, mmW 5G beamformer. The RF integrated circuit (RFIC) is highly integrated and contains 16 independent transmit and receive channels. The ADMV4928 supports eight horizontal and eight vertical polarized antennas via independent RFV and RFH input/outputs.

The ADMV4928 comes in a compact, 239-ball, 10 mm × 7 mm chip scale package ball grid array (CSP_BGA). The ADMV4928 operates over the −40°C to +95°C case temperature (TC) range. This CSP_BGA package enables the ability to heatsink the ADMV4928 from the topside of the package for the most efficient thermal heatsinking and to allow flexible antenna placement on the opposite side of the printed circuit board (PCB).
