- Fully featured evaluation board for the ADMV4821
- On-board SDP-S connector for SPI control
- 5 V operation through LDO regulators
- ACE software interface for SPI control
The ADMV4821-EVALZ evaluation board incorporates the ADMV4821 silicon germanium (SiGe), 24 GHz to 29.5 GHz, 5G beamformer with low dropout (LDO) regulators, level shifters, and an EVAL-SDP-CS1Z (SDP-S) controller board to allow the simplified and efficient evaluation of the ADMV4821. The RF IC is highly integrated and contains 16 independent transmitter and receiver channels. The device supports eight horizontal and eight vertical polarized antennas via independent RFV and RFH input/outputs (I/Os). The chip can be programmed using a 3-wire or 4‑wire serial port interface (SPI). The SDP-S controller allows the user to interface with the ADMV4821 SPI through the Analog Devices, Inc., Analysis, Control, Evaluation (ACE) software. The level shifters translate the 1.8 V chip logic level to the 3.3 V SDP-S logic level. The LDO regulators allow the ADMV4821 to be powered on by a single supply.
