Product Details

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 the user guide when using the ADMV8818-EVALZ.
