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.

This user guide serves as the main source of information for system engineers and software developers using the ADXBAND16EBZ. This platform contains four AD9084 software-defined, direct sampling mixed-signal front end (MxFE), including an RF front end, clocking, and power circuitry. Common target applications are phased array radars, electronic warfare, and ground-based SATCOM. The receive and transmit RF front ends have bypass configurations that allow customized frequency ranges of less than 8GHz up to 18GHz.

The ADXBAND16EBZ highlights a complete system solution. This platform is intended as a testbed for demonstrating multichip synchronization as well as the implementation of system-level calibrations and signal processing algorithms. The system is designed to mate with a Xilinx VCU118 evaluation board, which features the Virtex UltraScale+ XCVU9P field-programmable gate array (FPGA), with provided reference software, hardware design language (HDL) code, and MATLAB system-level interfacing.

A 16 transmit and 16 receive calibration board (ADXBAND16EBZCAL) can be used to develop system-level calibration algorithms to demonstrate power-up phase determinism. The calibration board demonstrates combined-channel dynamic range, spurious, and phase noise improvements that can also be controlled via a MATLAB add-on when connected to the peripheral module (PMOD) interface of the VCU118.
