Product Details
This user guide describes the EVAL-ADGM1304SDZ evaluation board for the ADGM1304, a wideband, single-pole, four-throw (SP4T), microelectromechanical systems (MEMS) switch, and a control chip that are copackaged in a compact, 24-lead, 5 mm × 4 mm × 0.95 mm, lead frame chip scale package (LFCSP). The SP4T switch uses Analog Devices, Inc., MEMS switch technology and provides optimal bandwidth performance, power handling capability, and linearity for radio frequency (RF) applications. The control chip generates the high voltage signals required by the MEMS switch and allows the user to control operation through a flexible, complementary metal-oxide semiconductor (CMOS)-compliant or low voltage transistor to transistor logic (LVTTL)-compliant parallel interface, as well as via a serial peripheral interface (SPI). Multiple ADGM1304 devices can be daisy-chained together to enable the configuration of multiple devices with a minimal amount of digital lines.
For the SPI interface, the evaluation board connects to the universal serial bus (USB) port of a PC via the system demonstration platform (SDP) board. The EVAL-SDP-CB1Z board (SDP-Bcontroller board) is available for order on the Analog Devices website at www.analog.com/SDP-B.
The EVAL-ADGM1304SDZ comes fitted with connectors for RF and control signals, and links to allow the user to control the operation of the switch and evaluate the performance of the ADGM1304.
