New National Instruments Hardware and Software Provide Dramatic Advances from Baseband to RF Engineers and scientists now can generate RF and baseband signals more than 300 times faster with the new ...

Despite the need for an IC, this ubiquitous interface between the modulator and audio-video signals has not been reduced to an integrated circuit. The major reasons for that deficiency are the ...

In Part 3 of RF Fundamentals, we will focus on the challenges related to the need to generate and demodulate analog and digitally modulated signals in the RF signal chain. We’ll review CW signal ...

A signal generator, a general-purpose piece of test equipment, performs numerous measurements for a variety of applications requiring electromagnetic wave signals as stimuli. Its roots trace back to ...

There was a time — not long ago — when radio and even wired communications depended solely upon Morse code with OOK (on off keying). Modulating RF signals led to practical commercial radio stations ...

Tektronix has rolled out the RTX130A, an integrated MPEG and RF signal generator offering both unmodulated and RF modulated playout of MPEG transport streams, supporting both cable (QAM A, B & C) and ...

The system in Figure 2 uses the ADF4372 PLL (see Figure 5), a wideband synthesizer with integrated VCO, that allows the implementation of fractional-N or integer-N frequency synthesizers when used ...

As the number of higher-throughput applications grows, so does the need for wider bandwidth and network coverage in wireless systems. Given limited spectrum allocation, wireless communication ...

Most of us know that to get the best possible WiFi signal, you want there to be as few walls as possible between you and the Access Point. But that might soon change, as researchers at MIT have found ...

Modern radio frequency (RF) components introduce many challenges to outsourced semiconductor assembly and test (OSAT) suppliers whose objective is to ensure products are assembled and tested to meet ...
