This is one in a series about trends in how signals get to the transmitter. Ted Nahil is U.S. sales representative of 2wcom Systems GmbH. He has served as chief engineer or director of engineering at ...

Narrowband filtering is an excellent tool for obtaining useful data of weak signals in noisy environments. Working for a small aerospace company, the problem of receiving weak telemetry signals is a ...

One extremely important yet not widely known characteristic of today’s high-performance RF signal analyzers is their use of a range of intermediate frequency (IF) filter bandwidth settings. IF ...

Multi-kilometre machine-to-machine communications special interest group (SIG) Weightless has decided to pursue ultra-narrow-band (UNB) comms in free-to-use ISM bands, rather than ‘white space’ radio ...

The HX1 from Radiometrix is a narrow band VHF radio transmitter module designed for use in various data-transfer applications. When used in conjunction with the matching RX1, BiM1R, or CVR1 receiver ...

This application note presents the TH7122 and TH71221 transceivers used in narrow band FSK applications. It briefly describes the narrow band considerations, the VCO design, PLL set-up, as well as the ...

The proliferation of wireless devices and an unrelenting demand for higher data rates have placed a significant strain on the RF spectrum. As bandwidth requirements for RF components and systems ...

The many technical factors that must be assessed in 5G antenna design, including their interactions. Further physical/environmental considerations for both the antenna and the entire system. In the ...
