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 […]
Analog IC Tips
Technology boosts on-board antenna performance up to 2 dB
New technology is said to deliver significantly better antenna performance. This innovation is particularly suited to designs with shorter ground planes, allowing IoT and other device designers to field a wider range of smaller devices that would otherwise not have been able to meet certain stringent carrier certification requirements. Taoglas Boost uses a new technique […]
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 […]

GaAs digital step attenuators from DC-40 GHz
The DSA family of GaAs digital step attenuators is intended to ease the design of high dynamic range receivers and instrumentation. These applications often must accomplish gain control of 50dB or more. Fine step DSAs (e.g., 0.5dB Least Significant Bit [LSB]) are often used for these applications. However, when a large attenuation change is needed, it […]
Electrical noise, Part 2: Additional perspectives
In Part 1, we looked at some facets of noise: sources, external versus internal (intrinsic) noise, and equations. Part 2 goes further into noise specifics. Q: What are some of the types of noise? A: It’s a long list. The same noise may have different names depending on the perspective of the person describing it, […]
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 […]
Spring pin socket for DC/DC converters handles 25 A
A new socket addresses high current requirements for dual dc-dc converters. The SBT-DC/DC-9002 uses a contactor that is a spring pin with 136-gm actuation force per pin and cycle life of 250,000 insertions. The current capacity of each contactor is 25 A at 20°C temperature rise. Socket temperature range is -55 to +150°C. The socket […]
Active noise cancellation, Part 2: Implementation
Part 1 of this FAQ looked at the basic concept of active noise cancellation, how it might be implemented in principle using analog circuitry, and the harsh reality of actually providing the ANC function. Part 2 looks at modern ANC systems and how they function, as well as their practical issues. Q: Is ANC using […]
New low noise amplifier and phase shifter MMICs added to line
Custom MMIC has added to their LNA and Phase Shifter MMIC portfolio with the CMD270P3 and CMD174. The CMD270P3 is a C Band, 4-8 GHz low noise amplifier housed in a leadless 3×3 mm plastic surface mount package. The LNA delivers greater than 16 dB of gain with a corresponding output 1 dB compression point of +18 […]
