Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADMV1228BBCZ is a 24.0 GHz to 29.5 GHz, mmW 5G dual-channel up-converter, dual-channel down-converter and beamformers integrated on a single chip. The RF integrated circuit (RFIC), in a 2x8 configuration, integrates two transmit/receive streams (2T2R) and 16 separate TX and RX beamforming channels to support both single - and dual-polarized array designs.

The on-chip transmit-receive switch connects each polarized upconverter RF output and downconverter RF input to eight separate channels via a 1:8 power splitter/synthesizer.
