Maxim's Essential Solutions Anticipate the Next-Generation Cellular Network

Maxim Integrated Products (NASDAQ: MXIM) announces several essential HetNet solutions needed for next-generation base-station equipment. The solutions include single-chip multiband radio transceivers, broadband gain blocks, direct RF synthesis DACs, and intelligent, digital, point-of-load controllers.

The cellular radio access network (RAN) is evolving to a heterogeneous network that demands a set of diverse analog and mixed-signal base-station solutions required for the main radio signal paths, baseband processing support, and power-conversion nodes. Maxim has anticipated the HetNet evolution and offers new solutions that deliver dense analog integration with high dynamic performance, low power, and high reliability.

HetNet is the coordinated deployment of critical 3G/4G wireless infrastructure elements comprising macro cell and small cell base stations, residential femto cells, and mobile backhaul. The network elements work in concert to deliver the high data throughput, high mobility, and the exceptional quality of experience that mobile broadband subscribers expect from the 3G/4G network. With exploding mobile media and data consumption patterns, subscribers will experience ubiquitous, reliable, and seamless connectivity from the HetNet architecture.

Selection of Maxim Solutions for the HetNet
  •     MAX2550–MAX2553 single-chip small-cell radio transceivers improve residential coverage and network capacity.
  •     MAX5879 direct RF synthesis DAC for multicarrier, multiband, and multistandard macro cell, small cell, and wireless backhaul transmitters; allows designers to develop a fully digital RF transmitter on a common hardware platform.
  •     MAX2870 ultra-wideband 23.5MHz to 6000MHz synthesizer with integrated VCO enables multiband LO frequency synthesis in base-station radios.
  •     MAX15301 InTune™ digital point-of-load controller with automatic compensation, integrated FET driver, and integrated PMBus™ telemetry delivers high-efficiency, intelligent, power-management nodes to radio and baseband units.
  •     The MAX2612–MAX2616 broadband, 40MHz to 4000MHz gain blocks deliver exceptional gain flatness, noise figure, and linearity; ideal for general-purpose RF amplifier applications in base-station and wireless backhaul radios.
Industry Commentary
  •     J. Madden, Principal Analyst of Mobile Experts said: "During 2010, the number of terabytes of mobile data exceeded the terabytes of voice data for the first time. And with the tsunami of demand for mobile data, operators are changing their focus to indoor and small-cell deployments to increase capacity. The network of the future is a 'HetNet.'" (Madden, J., "Semiconductors for Small Cells," Mobile Experts, October 2011, p. 14.)
  •     Vickram Vathulya, Managing Director in Maxim's Communications Solutions Group explained: "Maxim is in a unique position. We are leveraging our experience in IC integration to deliver disruptive high-performance technologies and differentiated solutions for a successful HetNet rollout."

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
