Analog Devices, Inc. today introduced the ADRF6806 and ADRF6807 quadrature demodulators featuring the industry’s highest dynamic range and integration, which is effective for a wide range of broadband communication applications such as cellular infrastructure and microwave point-to-point radios. The latest members of ADI’s RF IC portfolio, the ADRF6806 demodulator operates in the 50-MHz to 525-MHz range, and the ADRF6807 demodulator operates ...

Pentek, Inc., today announced its fastest ever multichannel data converter with digital down and up converters. With two channels each of 12-bit, 500 MHz A/D and 16-bit, 800 MHz D/A, the Model 71651 delivers more than twice the bandwidth of Pentek’s previous data converters. As a member of the popular Cobalt™ family of high-performance XMC modules, the Model 71651 has a Xilinx Virtex-6 FPGA at its core. The FPGA is preconfigured with data acq...

Linear Technology introduces the LTM8052, a 36V input constant frequency step-down µModule® regulator with an adjustable output current limit up to 5A. The adjustable current limit helps system designers set the maximum power delivered to a load, minimizing the output rating of the upstream AC/DC or DC/DC power supply.

M/A-COM Technology Solutions Inc. introduced today a new set of voltage controlled oscillators (VCOs) for radio applications. The VCOs are ideal for point-to-point radio, point to multipoint radio, communications systems, and low phase noise applications. The InGaP HBT-based VCOs are easily integrated into a phase lock loop, using a divide-by-two output.

Atmel Corporation announces the availability of an ultra-small XDFN (Extremely Thin Dual Flat No Leads) package including a 363-bit read/write transponder IDIC. The transponder IDIC ATA5577M1 is a high-volume low-frequency (LF, 100-150kHz) RFID device designed for small tag applications including animal ID ear and bolus tags, standard key fobs or clamshell cards for access control solutions. Measuring at 2mm x 1.5mm x 0.37mm, the XDFN package is ...

Rakon’s ‘Mercury’ series of low cost OCXOs bridges a major gap in the market between ultra-stable TCXOs and traditional higher end OCXOs, in terms of cost, stability, size, weight, and power consumption. Using state of the art VLSI techniques, this ASIC-based patented design is a disruptive technology enabling a considerable size reduction in OCXOs. Mercury is also significantly lower in cost than traditional OCXOs, which can consume up to ...

Building on the performance of its true single core high bandwidth family of ADCs with direct RF sampling, e2v announces the launch of EV12AS200, a 12-bit 1.5 GSPS analogue to digital converter. The new ADC combines the benefits of direct RF sampling up to L band, calibration free stable performance versus temperature and a wider choice of ADC input driving options, thanks to the lowest input voltage range on the market for 12bit GSPS ADCs.

GreenPeak makes it easy for CE manufacturers and MSOs to introduce low cost and robust RF4CE remote control solutions. With the launch of three new chips, GreenPeak allows the development of robust and low cost ZigBee RF4CE remote control applications for TV’s and set-top boxes, addressing an overall one billion unit annual market.

Linear Technology announces the LTC6946, the first device in a family of high performance integer-N frequency synthesizers with integrated VCO, delivering -226dBc/Hz normalized closed-loop in-band phase noise, superior -274dBc/Hz normalized in-band 1/f noise, and best-in-class -103dBc spurious output. In a typical 900MHz application, these performance attributes help to achieve a closed-loop phase noise of -100dBc/Hz at 1kHz offset. The device is...

STMicroelectronics has announced new radio-frequency (RF) power transistors built using an advanced technology that increases performance, ruggedness and reliability in vital demanding applications such as government communications, private mobile radio as used by emergency services, and L-band satellite uplink equipment.
