The ADGM1144 is a wideband, single-pole, four-throw (SP4T) switch, fabricated using Analog Devices, Inc., microelectromechanical system (MEMS) switch technology. This technology enables a small form factor, wide RF bandwidth, highly linear, low insertion loss switch that is operational down to 0 Hz/DC, making it an ideal solution for a wide range of RF and precision equipment switching needs.

An integrated driver chip generates a high voltage to an electrostatically actuate switch that can be controlled by a parallel interface and a serial peripheral interface (SPI). All four switches are independently controllable.

The device is packaged in a 24-lead, 5 mm × 4 mm × 1.0 mm land grid array package (LGA).

The ADGM1144 has integrated 10 MΩ resistors required for floating node avoidance. The presence of these integrated 10 MΩ resistors saves board space and eliminates floating nodes on the switch. To ensure optimum operation of the ADGM1144, refer to the Critical Operational Requirements section of the data sheet.

Throughout this data sheet, multifunction pins, such as IN1/SDI, are referred to either by the entire pin name or by a single function of the pin, for example IN1, when only that function is relevant.

Product Detail

The user guide describes the EVAL-ADGM1144SDZ for the ADGM1144, a dual-chip, RF switching solution containing a single-pole, four-throw (SP4T), microelectromechanical systems (MEMS) switch, and a control chip copackaged in a compact, 5.00 mm × 4.00 mm × 1.0 mm, LGA package.

The SP4T switch uses Analog Devices, Inc., MEMS switch technology, providing optimum performance in terms of bandwidth, power handling capability, and linearity for RF applications. The control chip generates the high-voltage signals needed for the MEMS switch and allows the user to control its operation through a simple and flexible complementary metal-oxide semiconductor (CMOS)/low voltage transistor to transistor logic (LVTTL)-compliant parallel-interface as well as through a serial-peripheral interface (SPI). It is possible to daisy-chain multiple ADGM1144 devices together to enable the configuration of multiple devices with a minimal number of digital lines.

For SPI, the EVAL-ADGM1144SDZ connects to the USB port of a PC via the SDP board. The EVAL-SDP-CB1Z board (SDP-B controller board) is available to order at the Analog Devices website.

The EVAL-ADGM1144SDZ comes fitted with connectors for RF and control signals as well as links to control the operation of the switch and evaluate its performance.

For full details on the ADGM1144, see the ADGM1144 data sheet, which must be consulted in conjunction with the user guide when using the EVAL-ADGM1144SDZ.
