ANALOG DEVICES DEBUTS INDUSTRY’S HIGHEST PERFORMING 13 GHZ PLL SYNTHESIZER

Analog Devices, Inc. (ADI) a global leader in high-performance semiconductors for signal-processing applications, today announced the industry’s highest performance 13 GHz PLL synthesizer. The ADF4159 achieves breakthrough phase detector operating frequency of 110 MHz and simultaneously consumes less than 100 mW of power, which is 5 times less than competitive solutions. In addition, the ADF4159 contains a 25-bit fixed modulus as well as on-chip functionality to generate highly linear ramp profiles, making it an ideal solution for Frequency Modulated Continuous Wave (FMCW) radar applications, including automotive radar systems, microwave Point-to-Point (PtP) systems, communications instrumentation and test equipment.

“Designers of FMCW radar systems, microwave Point-to-Point communications and test equipment require high frequency solutions that are capable of operating in very high phase detector frequencies without any sacrifice in power consumption,” said Peter Real, vice president, Linear and RF Group, Analog Devices, Inc. “As the latest member of ADI’s leading family of PLL synthesizers, the ADF4159 represents an ideal solution for these applications by delivering best-in-class phase-detector frequency of operation and power consumption.”

Featured in Analog Devices Booth #1725, the ADF4159 Fractional-N PLL Synthesizer consists of a low-noise digital phase frequency detector (PFD), precision charge pump and a programmable reference divider. It can be used to implement frequency shift keying (FSK) and phase shift keying (PSK) modulation. There are also a number of frequency sweep modes available, which generate various waveforms in the frequency domain, such as sawtooth and triangular waveforms. The ADF4159 features cycle slip reduction circuitry, which leads to faster lock times, without the need for modification to the loop filter.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.
