The ADGM1304 is a wideband, single-pole, four-throw (SP4T) switch, fabricated using Analog Devices, Inc., microelectro-mechanical system (MEMS) switch technology. This technology enables a small form factor, wide RF bandwidth, highly linear, low insertion loss switch that is operational from 0 Hz/dc to 14 GHz, making the ADGM1304 an ideal solution for a wide range of RF and precision equipment switching needs.An integrated driver chip generates a high voltage to electrostatically actuate a 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 ? 0.95 mm, lead frame chip-scale package (LFCSP).To ensure optimum operation of the ADGM1304, the Critical Operational Requirements section must be followed exactly.The on resistance (RON) performance of the ADGM1304 is affected by device to device variation, channel to channel variation, cycle actuations, settling time post turn on, bias voltage, and temperature changes.APPLICATIONS Relay replacements Automatic test equipment: RF/high speed digital and mixed signals Load and probe boards: RF/high speed digital and mixed signals RF test instrumentation Reconfigurable filters and attenuators High performance RF switching

The ADGS1212 contains four independent single-pole/single-throw(SPST) switches. A serial peripheral interface (SPI)controls the switches. The SPI interface has robust error detectionfeatures such as cyclic redundancy check (CRC) error detection,invalid read/write address detection, and SCLK count errordetection.It is possible to daisy-chain multiple ADGS1212 devices together.Daisy-chain mode enables the configuration of multiple deviceswith minimal digital lines. The ADGS1212 can also operate inburst mode to decrease the time between SPI commands.iCMOS construction ensures ultralow power dissipation, makingthe device ideal for portable and battery-powered instruments.Each switch conducts equally well in both directions when on,and each switch has an input signal range that extends to thesupplies.In the off condition, signal levels up to the supplies are blocked.The ultralow capacitance and charge injection of these switchesmake them ideal solutions for data acquisition and sample-andholdapplications where low glitch and fast settling are required.Fast switching speed coupled with high signal bandwidth makethe device suitable for video signal switching.Multifunction pin names may be referenced by their relevantfunction only.Product Highlights SPI interface removes the need for parallel conversion, logic traces, and reduces the general-purpose input/output (GPIO) channel count. Daisy-chain mode removes additional logic traces when multiple devices are used. CRC error detection, invalid read/write address detection, and SCLK count error detection ensure a robust digital interface. CRC and error detection capabilities allow the ADGS1212 to be used in safety critical systems. Guaranteed break-before-make switching allows the the ADGS1212 to be used in multiplexer configurations with external wiring. The ADGS1212 1.8 V logic compatibility with 2.7 V ?

The HMC546MS8G(E) is a low-cost SPDT switch in 8-lead MSOP8G surface mount package for use in transmit-receive applications which require very low distortion at high signal power levels, up to 10 watts. The device can control signals from 200 - 2200 MHz* and is especially suited for cellular booster, PMR and automotive telematic applications. The design provides exceptional P0.1 dB of +40 dBm and +65 dBm IIP3 on the Transmit (Tx) port. The failsafe topology allows the switch to provide a low loss path from RFC to Tx, when no DC power is available.*Specifications and data reflect HMC546MS8G(E) measured using the respective application circuits for each designated band found herein.Applications LNA Protection, WiMAX, WiBro Cellular/PCS/3G Infrastructure Private Mobile Radio and Public Safety Handsets Automotive Telematics
