  1. Using Microwave And Millimeter Wave Radiometers

    Microwave radiometric sensors are devices used to detect electromagnetic energy. This white paper expresses the reasoning for certain radiometer calibrations and other modes of operation in regards to the sensor’s subsystems.

  2. Choosing Blocking Capacitors – It’s More Than Just Values

    Capacitors are a fundamental building block for RF and microwave systems as they are often used to create filters, generate DC protection, and build bypass networks. Designers often use approximate equations to predict capacitor values and find the final RF performance. However, as a system constantly requires higher performance levels, these assumptions are no longer valid. This article discusses how to improve RF performance by using fewer capacitors that block DC and pass AC current, and how to choose these capacitors based on real world performance.

  3. Mall Communication Solutions

    At shopping malls, consumers also are able to find various types of entertainment, dining options, spa services, childcare, etc. This white paper presents DeltaNode’s Distributed Antenna Systems (DAS) solution for meeting these wireless communications difficulties.

  4. RF Power Measurements In The Field

    Measuring RF power in a field environment can be accomplished accurately and inexpensively. It also involves a great deal of care and proper training to ensure equipment is accurately measured. Either way, accurate field power measurements will ensure transmitting equipment is operating properly.

  5. Rotman Lens Design And Simulation In Software

    Since its invention in the early 1960s, the Rotman Lens has proven itself to be a useful beamformer for designers of electronically scanned arrays. Inherent in its design is a true time delay phase shift capability that is independent of frequency and removes the need for costly phase shifters to steer a beam over wide angles. This article uses the developed software to design and analyze a microstrip Rotman Lens for the Ku band.

  6. 5G Or .11ax?

    Why are names like Wi-Fi, Bluetooth and LTE more well-known than 5G or Zigbee when they all play a huge role in our daily lives? Both 5G and Wi-Fi have very particular characteristics that will be beneficial for connecting devices to the internet. This white paper offers a different perspective on the “battle” between these two types of technology, and how to leverage each to exploit the most advantages.

  7. Considerations For Connector Design In Mobile And Patient-Worn Medical Devices

    In medical device design, everything must be safe for both the patient and the operator, and often, devices face years of additional testing, so reducing any risks in the designer’s approach is extremely important. This white paper discusses the rising need for mobile and patient worn devices, and offers recommendations on the proper approach to designing interconnect solutions for these applications.

  8. The Increasing Impact Of Speed And Miniaturization On Rugged Connector Selection

    Design engineers are challenged to pump increasing amounts of data through smaller and smaller spaces. This paper provides a step-by-step process for rugged connector selection that takes the new realities engineers face today into consideration, such as speed and miniaturization.

  9. Why Satellite Ground Stations Are So Important To Mission Success

    Satellite ground stations play an important role in making SATCOM possible by providing real-time communication with satellites, and can serve as command and control centers for a satellite network. Simply put, the ground station (or network of stations) is the “brain” of the entire satellite network. 

  10. The Road To 5G Is Paved With Fiber

    The most demanding ­5G applications will require fiber for each small cell, but the exact fiber cable requirements for each deployment will differ based on local geography and expected demand. This white paper will discuss the important uses of fiber in 5G technologies, and provide insight on how to calculate the amount of fiber needed for 5G in metropolitan areas.
