High Harmonic-rejection Matching Filters for Quad-band Power Amplifiers

In this article, matching filters for GSM amplifiers capable of providing large harmonic rejection are demonstrated using M/A-COM’s high Q GaAs MMIC technology. The matching filters are designed for the output of the quad-band (GSM 850/900/1800/1900 MH...
Recent advances in mobile phone RF modules have been made for the miniaturization and integration of components in such a manner that they can address all of the global standards. The stringent specifications for the different systems have to be met using inexpensive surface-mount plastic modules, which integrate diverse...
