Answers to RF Cafe Quiz #67

RF Engineering Quizzes - RF CafeAll RF Cafe Quizzes make great fodder for employment interviews for technicians or engineers - particularly those who are fresh out of school or are relatively new to the work world. Come to think of it, they would make equally excellent study material for the same persons who are going to be interviewed for a job. Bonne chance, Viel Glück, がんばろう, buena suerte, удачи, in bocca al lupo, 행운을 빕니다, ádh mór, בהצלחה, lykke til, 祝你好運. Well, you know what I mean: Good luck!

RF Cafe Quiz #67: RF & Analog Company Name Change HistoryThis quiz tests your knowledge on the history of familiar electronics products companies' name changes (aka etymology). Many of you have lived through the plethora of acquisitions, mergers, and name changes represented here. There might be more than one correct answer. You might need a motion sickness pill when navigating all the changes. Wikipedia is used as the reference because I know the historical information presented there is accurate (enough).


1.  Skyworks Solutions designs and manufactures a wide variety of amplifiers, switches, front-end modules, and other ICs and modules for wireless systems. From which company(s) did it come?

Conexant Systems logo - RF Cafelpha Industries logo - RF Cafeb & d)  Conexant Systems

Skyworks Solutions was formed as a separate company in 2002 following the merger of Alpha Industries and Conexant Systems.



2.  Keysight Technologies is a premier maker of test equipment of all types. It has undergone multiple name changes. What was its original name?

Agilent Technologies logo - RF CafeHewlett Packard logo - RF Cafeb & c)  Agilent Technologies & Hewlett Packard

Keysight Technologies in 2014 was born out of Agilent Technologies, which itself in 2001 was a spawn of Hewlett Packard. I'll never forgive HP for abandoning its test equipment brand in favor of computers.



3.  Qorvo manufactures RFICs and components for the cellphone and wireless markets. Whence came it?
