The dual VGA variable gain amplifier is unique with its features like 1 db attenuation steps over 31 db using a 5 bit control input with a 0.25 db gain flateness over 100 Mhz BW. This chip also has a four step rapid gain control which is programmable by the designer using SPI interface plus a 2 bit digital input. The BW 50 to 1000 Mhz at a noise figure of 5.6 db with 2 independant VGA's makes it very attractive and compact for various RF applications. This chip has a power save feature where the supply can be reduced to 3.3 volts and usefull feature for mobile applications. over all this is a great design by Maxim designers in the field of wide band RF amplifiers. Soon we may expect these devices available at a lower noise figure from Maxim semiconductors.
