37.0 GHz to 43.5 GHz 2 Transmit/2 Receive Dual Polarization UDC + Beamformer

The ADMV1239 is a 37.0 GHz to 43.5 GHz, mmW 5G dual channel upconverter, dual channel downconverter and beamformer integrated on a single chip. The RF integrated circuit (RFIC) combines two transmit/receive streams (2T2R) with 16 independent TX and RX beamformer channels in a 2 by 8 configuration supporting both single and dual polarization array designs.

The on-chip transmit receive switches connect the upconverter RF output and downconverter RF input for each polarization into eight independent channels via the 1:8 power splitters/combiners.

The ADMV1239 comes in a compact chip scale ball grid array package. The ADMV1239 operates over the −40°C to +95°C case temperature (TC) range. This package allows heatsinking the ADMV1239 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).
