ADMV8913

• Fully featured evaluation board for the ADMV8913 
• On-board SDP-S connector for the SPI 
• Evaluation using on-board LDO regulators powered by the USB ACE software interface for SPI control 

The ADMV8913-EVALZ is available for evaluating the ADMV8913 digitally tunable, high-pass filter (HPF) and low-pass filter (LPF). The ADMV8913-EVALZ incorporates the ADMV8913 chip, as well as a negative voltage generator, low dropout (LDO) regulators, and an interface to the EVAL-SDP-CS1Z (SDP-S) system demonstration platform (SDP) to allow simple and efficient evaluation. The negative voltage generator and LDO regulators allow the ADMV8913 to be powered by either the 5 V USB supply voltage from the PC via the SDP-S or by using two external power supplies.

The ADMV8913 is a fully monolithic microwave integrated circuit (MMIC) that features a digitally selectable frequency of operation. The chip has an integrated HPF followed by an integrated LPF that allows a pass-band response within the X band frequency range. The chip can be programmed using either the parallel logic interface or a 4-wire serial port interface (SPI). The SDP-S controller allows the user to interface with the ADMV8913 SPI through the Analog Devices, Inc., Analysis | Control | Evaluation (ACE) software.

For full details on the ADMV8913, see the ADMV8913 data sheet, which must be consulted in conjunction with the user guide when using the ADMV8913-EVALZ.

The ADXBAND16EBZ contains four AD9084 mixed‑signal front‑end devices, including the RF front end, clocking, and power circuitry. The ADXBAND16EBZ serves as a complete system solution targeting common applications such as phased‑array radars, wideband systems, and ground‑based SATCOM. Its primary target application is a 16‑Tx/16‑Rx direct X‑band sampling phased array.

The platform is intended as a testbed for demonstrating multi‑chip synchronization, as well as implementing system‑level calibrations, beamforming algorithms, and other signal‑processing techniques. The system is designed to interface with the VCU118 Evaluation Board from Xilinx^®, which features the Virtex^® UltraScale+™ XCVU9P FPGA, along with provided reference software, HDL code, and MATLAB system‑level interfaces.

A 16‑Tx/16‑Rx Calibration Board can be used to develop system‑level calibration algorithms, including demonstrations of power‑up phase determinism. The Calibration Board provides improvements in combined‑channel dynamic range, spurious performance, and phase noise, and can be controlled via a MATLAB add‑on when connected to the PMOD interface of the VCU118.
