IDT offers high-performance and full-featured radio frequency (RF) products helping to address unwanted interference from an increasingly crowded radio spectrum. Today’s higher data rates drive the need for better radio signal-to-noise ratios, which translates to the need for IDT’s higher linearity RF components. IDT’s patented RF solutions with unique technical innovations address the evolving needs of a wide range of applications, including cellular 4G base stations, communications systems, microwave (RF/IF), CATV, test and measurement, and industrial.

Industry-leading RF Innovations

Glitch-Free™ Technology: IDT’s digital step attenuators (DSA) virtually eliminate transient overshoot that occurs during MSB attenuation state transi­tions of standard DSAs. With Glitch-Free technology, amplifier damage and loss of information at the ADC are avoided.

FlatNoise™ Technology: IDT’s variable gain amplifier (VGA) noise figure is kept virtually flat in the criti­cal region, while gain is reduced. This greatly eases design constraints for radio engineers by enhancing signal-to-noise ratio (SNR).

Zero-Distortion™ Technology: IDT’s RF amplifiers and RF mixers improve SNR by reducing the noise floor and third order intermodulation distortion. This is important for crowded spectrum envi­ronments, as it enhances quality-of-service (QoS) and frees up under-utilized spectrum.

K|Z| Constant Impedance Technology: IDT’s RF switches maintain nearly constant impedance when switching between RF ports. By controlling the impedance during the switching process voltage standing wave ratio (VSWR), transients are minimized. This improves switch reliability, reduces voltage stresses on downstream components, and improves overall system performance.

KLIN Constant Linearity Technology: IDT’s variable gain amplifiers maintain constant high linearity as gain is adjusted. As the gain is reduced, the linearity (OIP3) remains constant in the critical region. This prevents in­termodulation distortion from degrading as the gain is reduced.
