IQ modulator design needs measurement accuracy, says Linear Tech

How to optimise digital modulation accuracy in an IQ modulator? Bruce Hemp and Peter Stroet from Linear Technology describe how a vector signal analyser helps optimise EVM performance of the LTC5598 direct quadrature modulator. EVM, or error vector magnitude, is essentially a scalar measurement of digital modulation accuracy, an important figure of merit for any ...

Panasonic offers small capacitor with big values

A range of aluminium electrolytic capacitors from Panasonic Automotive & Industrial System are available in can sizes measuring down to 4×5.8mm. This is a significant reduction in can size on previous capacitors, said the supplier. The FKS series offers increased capacitance values than previous products. For example, the new 25V 33µF FKS capacitor, which comes ...

Chip supplier makes finished embedded product move

Atmel has formed a partnership with French embedded systems design house and manufacturer Lacroix Electronics. The aim seems to be to design its microcontrollers and other ICs into embedded systems products for industrial applications and radio communications. As a result the semiconductor company will be able to offer complete system products and not only ICs. ...

Rohde & Schwarz targets testing of 5G radio channels

Rohde & Schwarz targets testing of 5G radio channels

The spectrum and channel bandwidth requirements of 5G mobile communications is raising test challenges. For example, 5G mobile radio will use microwave and millimeter‑wave frequencies and it will have larger channel bandwidth. According to Rohde & Schwarz, one of the test requirements of 5G will be channel sounding. “5G developers need to know the exact transmission path ...
