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.
