GENERAL DESCRIPTION

The ADMV8818-EVALZ is available for evaluating the
ADMV8818 digitally tunable, high-pass and low-pass filter.
The ADMV8818-EVALZ incorporates the ADMV8818 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 ADMV8818 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 ADMV8818 is a fully monolithic microwave integrated circuit
(MMIC) that features a digitally selectable frequency of operation.
The chip features four independently controlled high-pass and
low-pass filters that span from 2 GHz to 18 GHz. The chip can be
programmed using a 4-wire serial port interface (SPI). The SDP-S
controller allows the user to interface with the ADMV8818 SPI
through the Analog Devices, Inc., Analysis | Control | Evaluation
(ACE) software.
For full details on the ADMV8818, see the ADMV8818 data
sheet, which must be consulted in conjunction with this user
guide when using the ADMV8818-EVALZ.

    Label Function Use the CONFIGURATION section to initialize the ADMV8818-EVALZ. Load Settings from CSV: click the … button to select which CSV file to load into the CONFIGURATION section. Check to Load Settings: once a file has been selected, select this check box to load the CSV file contents into the CONFIGURATION section.
  • Page 7 If an external waveform generator is connected to the CSB_EXT port on the ADMV8818-EVALZ, the CSB_AUX pin has no effect and the CSB_EXT port takes precedence. Use the SFL Settings section to configure the SPI fast latch settings on the chip when in the SFL mode. Refer to the ADMV8818 data sheet for more information regarding the internal state machine and SFL mode functionality.

    UG-1921 PERFORMING THE EVALUATION ADMV8818-EVALZ QUICK START To set up the ADMV8818-EVALZ, take the following steps: Connect the RFIN and RFOUT ports to a network analyzer (or a similar instrument). Typically, RFIN and RFOUT are connected to Port 1 and Port 2 on the network analyzer, as shown in Figure 2.
