Remote Tuner Architecture Reduces Wiring Weight and Cost While Improving Noise Immunity

Wiring four antennas to the radio head unit in a traditional radio architecture requires up to 60 feet of copper cables. A new architecture detaches the tuners from the radio head unit, placing them near the antennas and serializing their outputs. This reduces the length of the wiring by roughly a factor of four. The overall effect is significantly lower weight and cost, improved noise immunity, reduced heat generation, and less complexity in the radio head unit.

Conductive Coatings Protect Circuitry from EM/RF and ESD

With the trend toward smaller and smaller electronic devices, unintentional EMI/RFI interference has become more of an issue. Shielding of these interferences is critical and coatings can be successfully applied as protection on the materials used. In this paper, the different sources of interference are explored, as well as how coatings can play a critical role in protecting these sensitive components and boards.

Six Axes of Calibration

In a system or on a lab bench, proper instrument calibration reduces the chances of false test results. Not all calibrations are equal, and six key factors affect quality, usefulness and cost. In Six Axes of Calibration, we highlight the importance and value of each factor. Download application note.

dB or not dB? Everything you ever wanted to know about decibels but were afraid to ask...

True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field strengths and more. What is a decibel and how should we use it in our calculations? This Application Note is intended as a refresher on the subject of decibels.

Antenna Basics

The antenna is the most intrinsic component of all RF systems, yet the principles of antenna design and wave propagation are rarely discussed outside the entry level engineering classes. Rohde & Schwarz has developed an educational white paper on Antenna Basics to reteach the basic principles in a simplified manner.
