Direct RF Sampling (DRFS) or Direct RF Conversion (DRFC) is the sampling of RF signals and conversion to digital signals without the need for an intermediate frequency (IF) stage to translate the frequency of the RF signals to a lower frequency more accessible to...
Direct digital synthesis (DDS), as used to denote a direct digital synthesizer device, is the use of digital-to-RF conversion to directly generate RF signals from digital signals. In some cases, DDS RF signals are fully modulated and ready to be amplified and sent...
Power Amplifiers (PAs) are essential components in most RF, microwave, and millimeter-wave sensing, communications, electronic warfare (EW), and directed energy weapons. PAs are used within a signal chain to add significant gain to the signal, typically within the...
RF switches are prevalent in many RF systems for a variety of uses. Switches are commonly used to switch between a receive or transmit channel at the port of an antenna, switch between filter channels, or used in matrices to switch test channels for high throughput...
Key Mixer Performance Parameters RF Mixers are 3-port frequency translation circuits that “mix” the signal inputs from two of its ports and outputs a third signal, along with other products, that is a function of the two inputs. We offer a variety of...
baluns RF transformers provide the very useful functions of an impedance transformation and a voltage step-up or step-down depending on the transformer design. RF transformers may have multiple conductive pathways, each with a unique coupling ratio,...
Signal Chain Discussion Series: Mixers, Upconverters, and Downconverters Frequency translation is an essential function needed in many signal chains. Superheterodyne circuits require frequency mixing into an intermediate frequency (IF) band and from the IF to an RF...
