The HMC951A is a compact gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), in-phase quadrature (I/Q) downconverter in a RoHS compliant package that operates from 5.6 GHz to 8.6 GHz. This device provides a small signal conversion gain of 13 dB with a noise figure of 2 dB and an image rejection of 32 dBc. The HMC951A uses a low noise amplifier (LNA) followed by an image mixer that is driven by a local oscillator (LO) buffer amplifier. The image reject mixer eliminates the need for a filter following the LNA and removes thermal noise at the image frequency. The IF1 and IF2 mixer outputs are provided and an external 90? hybrid is needed to select the required sideband. The I/Q mixer topology reduces the need for filtering of unwanted sideband. The HMC951A is a smaller alternative to hybrid style, single sideband (SSB) downconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface-mount manufacturing techniques.The HMC951A is available in 4 mm ? 4 mm, 24-lead lead frame chip scale package (LFCSP) and operates over the ?40?C to +85?C temperature range. An evaluation board for the HMC951A is also available upon request. Applications Point to point and point to multipoint radios Military radars, electronic warfare, and electronic intelligence Satellite communications Sensors

The EV-21569-SOM with low-cost evaluation and rapid prototyping of the ADSP-2156× Family (ADSP-21562/21563/21565/21566/21567/21569) of SHARC+ audio processors. It features the processor, memory, and power portions of the design and provides an easy-to-use plug-n-play reference design with all the key interfaces made available on three connectors for marrying to either the EV-SOMCRR-EZKIT carrier board or a custom carrier board. The EV-21569-SOM and EV-SOMCRR-EZKIT boards may be purchased as a bundle (EV-21569-EZKIT), providing fast and easy evaluation of the processor core and system peripherals/interfaces. The EV-21569-SOM module requires the CrossCore® Embedded Studio (CCES) development tools to enable developers to achieve faster time to market. The development environment aids advanced application code development and debug, such as: Create, compile, assemble, and link application programs written in C++, C, and assembly Load, run, step, halt, and set breakpoints in application programs Read and write data and program memory Read and write core and peripheral registers When used without the EV-SOMCRR-EZKIT carrier board, the EV-21569-SOM board requires an external in-circuit emulator (ICE-1000 or ICE-2000) be connected to the JTAG header.

The EV-21593-SOM enables evaluation and rapid prototyping of designs featuring the ADSP-2159x Family (ADSP-21591/ADSP-21593) of SHARC audio processors. It provides an easy-to-use plug-n-play reference design with expansion capabilities to interface to custom hardware ahead of the release of the processor itself. When the EV-21593-SOM board is plugged into the EV-SOMCRR-EZKIT carrier board, the resulting EZ-KIT® evaluation system (EV-21593-EZKIT) can be used for fast and easy evaluation of the processor core and system peripherals/interfaces. The EV-21593-SOM enables rapid prototyping for a wide range of applications, including immersive 3D sound and personal audio zones (PAZ), automotive active and road noise cancellation (ANC/RNC), voice-based user-interfaces and in-car communications (ICC), engine sound synthesis (ESS) and electric vehicle warning sound systems (EVWSS/AVAS). Additional applications include professional audio and soundbars / home AVRs (with 3D Object and Multi-Channel Audio) and enhanced conferencing systems. ADI offers several software modules (e.g., AEC/NR, microphone beamforming, pitch shifting, harmonic generators, wave players etc.), as well as complete software solutions that can be licensed, where users can develop/evaluate their audio and voice processing applications. ADI also offers 3rd party surround sound solutions that can be licensed on ADI’s SHARC processor families. Please visit ADI’s Software Solutions page for more information.

The LTC4227 offers ideal diode-OR and Hot Swap? functions for two power rails by controlling external Nchannel MOSFETs. MOSFETs acting as ideal diodes replace two high power Schottky diodes and the associated heat sinks, saving power and board area. A Hot Swap control MOSFET allows a board to be safely inserted and removed from a live backplane by limiting inrush current. The supply output is also protected against short-circuit faults with a fast acting current limit and internal timed circuit breaker.The LTC4227 regulates the forward voltage drop across the MOSFETs to ensure smooth current transfer from one supply to the other without oscillation. The ideal diodes turn on quickly to reduce the load voltage droop during supply switchover. If the input supply fails or is shorted, a fast turn-off minimizes reverse-current transients.The LTC4227 allows turn-on/off control, and reports fault and power good status for the supply.
