The company's RF portfolio includes TruPwr ( tm ) RMS power detectors and logarithmic amplifiers; DDS synthesizers; RF prescalers; variable gain amplifiers; ADC drivers, gain blocks, LNAs and other RF amplifiers.
Manufacturers of transistors and integrated circuits often divide their product lines into'linear'and'digital'lines . " Linear " here means " analog "; the linear line includes integrated circuits designed to process signals linearly, such as op-amps, audio amplifiers, and active filters, as well as a variety of signal processing circuits that implement nonlinear analog functions such as logarithmic amplifiers, analog multipliers, and peak detectors.
