A mobile phone jammer circuit usable with GSM1900 and an effective frequency range of 1930 MHz through 1990 MHz. The GSM1900 network is used in Canada, South America, and the United States (T-Mobile and AT&T).
The big list of electronic component and integrated circuit (IC) package types
Integrated circuit packages, the form an IC is manufactured in, are as wide and varied as a Donald Trump “alternative truth”. Below is the big list of integrated circuit (IC) package types including the package name, package full (official) name, remarks and notes, and a picture of diagram of the electronic package.
