  • Matched to 50 Ω, single-ended RF inputs/outputs and single-ended LO input
  • Fast TDD switching using TRX_x pins
  • On-chip temperature sensor for RX and TX automatic temperature compensation for Gain
  • Memory for TX and RX beam positions
  • NVM for phase and gain calibration
  • Upconversion mode
    • Sideband rejection and carrier feedthrough optimization
    • Envelope detector for LO feedthrough calibration
    • Single channel power detector
  • Downconversion mode
    • Integrated individual RX channel overload detection circuits
  • 3-wire or 4-wire SPI that supports up to 133 MHz SPI clock speed

The ADMV1228 is a 24.0 GHz to 29.5 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 ADMV1228 comes in a compact, chip scale ball grid array package. The ADMV1228 operates over the −40°C to +95°C case temperature (TC) range. This package allows heatsinking the ADMV1228 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).

Applications
