The Global Positioning System (GPS) is a worldwide, RF wireless-based system for determining where you are anywhere in the Earth’s surface if there is line-of-sight visibility to at least four of its orbiting satellites. The availability of GPS since its inception a few decades ago has not only enabled products and features which were simply […]

World’s smallest ceramic NB-IoT antenna covers three global bands
The first two antennas in the Extensis range of narrowband IoT (NB-IoT) antennas include the world’s smallest ceramic NB-IoT antenna that covers Bands 5, 8 and 20 simultaneously with a single matching configuration. The antennas are specifically designed for NB-IoT solutions. The low-profile, highly efficient NCP.5820 is a NB-IoT ceramic surface mount multiband antenna that […]
Filters suppress noise from 600 MHz to 2.7 GHz on audio lines
TDK Corporation has expanded the MAF1005G series of noise suppression filters for audio lines with four new MAF1005GAD-D types, which, thanks to their low DC resistance, feature a high rated current of up to 1.25 A. The new types employ TDK’s proprietary low-distortion ferrite that enables the new components to suppress noise at cellular frequencies from […]
One chip, multiple LTE signals for 3G, 4G, and 5G macro cell TDD base station work
Matt Purvis from ADI recently took us through a demo of a super-wideband RF transceiver chip that targets the expanding 5G telecom area. The point of the chip is to transmit multi-carrier LTE signals and to simplify the task of designing MIMO systems. Called the ADRV9009, it is a single-chip time division duplex (TDD) design […]
Inside look at a super-narrow band-pass filter-on-a-chip
The days of constructing bandpass filters from discrete components are pretty much over when it comes to the frequencies involved in modern wireless gear. That’s what makes the video we recently did with Alex Rabinovich from AVX interesting. Alex showed us a bandpass filter characteristic that’s super narrow, and the filter that creates also comes […]

RF power measurement, Part 2: What and how
Part 1 of this FAQ introduced some of the basic issues related to the measurement of RF power, which is a primary parameter in most RF designs. Part 2 continues the discussion, looking at RF waveforms and sensors. Q: The term “power” is fairly broad; what are the specifics? A: There are actually several basic […]
RF power measurement, Part 1: Why and where
When the subject is RF design, the word “power” dominates much of the discussion. This FAQ looks at some perspectives related to the measurement of this vital RF parameter. Not only is power and measuring it among the most important RF design considerations, but it is also generally difficult to assess accurately, and it is […]
PCIe Gen 4-compliant clock buffers powered from single 1.5 V/1.8 V supplies
Silicon Labs has introduced a new family of low-power PCI Express (PCIe) Gen 1/2/3/4 clock buffers that provide ultra-low jitter clock distribution in 1.5 V and 1.8 V applications. With additive jitter performance of 40 fs RMS (typical), Silicon Labs’ new Si532xx PCIe clock buffers provide more than 90 percent margin to stringent PCIe Gen 3 […]
