The HMC571LC5 is a compact GaAs MMIC I/Q downconverter in a leadless RoHS compliant SMT package. This device provides a small signal conversion gain of 9 dB with a noise figure of 3.5 dB and 18 dB of image rejection across the frequency band. The HMC571LC5 utilizes an LNA followed by an image reject mixer which is driven by an active x2 multiplier. The image reject mixer eliminates the need for a filter following the LNA, and removes thermal noise at the image frequency.I and Q mixer outputs are provided and an external 90° hybrid is needed to select the required sideband. The HMC571LC5 is a much smaller alternative to hybrid style image reject mixer downconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface mount manufacturing techniques.APPLICATIONS Point-to-Point Point-to-Multi-Point Radio Military Radar, EW & ELINT Satellite Communications

The ADuM4160 is a USB port isolator, based on Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics and are easily integrated with low and full speed USB-compatible peripheral devices.Many microcontrollers implement USB so that it presents only the D+ and D− lines to external pins. This is desirable in many cases because it minimizes external components and simplifies the design; however, this presents particular challenges when isolation is required. USB lines must automatically switch between actively driving D+/D−, receiving data, and allowing external resistors to set the idle state of the bus. The ADuM4160 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers. Data direction is determined on a packet-by-packet basis.The ADuM4160 uses the edge detection based iCoupler technology in conjunction with internal logic to implement a transparent, easily configured, upstream facing port isolator. Isolating an upstream facing port provides several advantages in simplicity, power management, and robust operation.The isolator has propagation delay comparable to that of a standard hub and cable. It operates with the supply voltage on either side ranging from 3.1 V to 5.5 V, allowing connection directly to VBUS by internally regulating the voltage to the signaling level. The ADuM4160 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing. The device has a low idle current; a suspend mode is not required.APPLICATIONS USB peripheral isolation Isolated USB hub Medical applications

The ADV3228/ADV3229 are high speed 8 × 8 analog crosspoint switch matrices. They offer a −3 dB large signal bandwidth of 750 MHz (ADV3228) and a slew rate of 2500 V/μs.The ADV3228/ADV3229 include eight independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs to prevent off channels from loading the output bus. The ADV3228 has a gain of +1, the ADV3229 has a gain of +2, and they both operate on voltage supplies of ±5 V. Channel switching is performed via a serial digital control that can accommodate daisy chaining of several devices or via a parallel control to allow updating of an individual output without reprogramming the entire array.The ADV3228/ADV3229 are available in the 72-lead LFCSP package over the extended industrial temperature range of −40°C to +85°C.Applications Routing of high speed signals including:       Video (NTSC, PAL, S, SECAM, YUV, RGB)       Compressed video (MPEG, wavelet)       3-level digital video (HDB3) Data communications Telecommunications
