APPLICATION PERSPECTIVE

Start with your applicationUnderstand Signal Chain Selection

Communications, test and measurement, and radar. Translate system requirements into device functions, then check specific models and operating conditions.

COMMUNICATION & RF FRONT END

Communications & RF Front Ends

Three independent RF functions: frequency selection, path switching and amplitude controlTunable filters select the operating passband, RF switches select signal paths, and digital step attenuators control signal amplitude. The three rows represent independent functions, not a fixed cascade; curves are conceptual symbols only.Tunable FiltersRF switchDigital step attenuatorSelect the operating passbandSelect the Signal PathControl signal amplitude010203
Three independent functional illustrations, not a fixed cascade; curves are not device responses or measured data.

For frequency selection, path switching and signal amplitude control, review operating frequency range, insertion loss, power conditions, control interfaces and system bandwidth.

Check these conditions first

  • Target frequency range and passband configuration; narrowband or wideband signal requirements.
  • Applicable insertion loss, bandwidth and configuration conditions.
  • RF path power, switch topology, and amplitude control requirements.

Functional relationships in signal acquisition and signal generationIn the upper path, the analog input becomes digital data through front-end conditioning and ADC conversion. In the lower path, digital data becomes an analog output through DAC conversion and output conditioning. Arrows indicate simplified functional direction only; the zeros and ones are not actual codes. Neither path is a validated reference circuit.01 / Signal Acquisition02 / Signal GenerationADCDAC010101010101Analog InputFront-end conditioningADC ConversionDigital DataDigital DataDAC conversionOutput ConditioningAnalog Output

From front-end conditioning and data acquisition to signal generation, select product categories according to system bandwidth, dynamic range, sampling, and output requirements.

Check these conditions first

  • Input signal range, front-end bandwidth and drive conditions.
  • Data conversion sampling rate, resolution and interface requirements.
  • Analog output range, load, and system clock conditions.

RADAR SYSTEMS

Radar Systems

Radar transmit/receive relationships and system functions to review togetherThe antenna transmits signals and receives target echoes. Gray dashed lines below associate three functions that must be reviewed together: front-end frequency selection, path control and signal acquisition. Dashed lines indicate functional relationships, not wiring, a fixed sequence or a complete reference design.Transmit signalTarget EchoAntennaTargetReview System Functions010101Front-End Frequency SelectionPath controlSignal Acquisition
Conceptual transmit/receive and functional relationships, not a complete reference design; dashed lines do not indicate wiring or a fixed device order.

Discuss frequency range, bandwidth, path control, clocking and data interface requirements for the RF front end and signal acquisition chain in the context of the specific system architecture.

Check these conditions first

  • Target frequency band, instantaneous bandwidth, and power conditions of the transmit and receive paths.
  • Front-end frequency selection, signal-path control and signal amplitude requirements.
  • System constraints linking acquisition, frequency support and data interfaces.

FROM REQUIREMENT TO DEVICE

Start selection with actual requirements

These diagrams support discussion of functional relationships. Specific device combinations, replacement compatibility, and achievable performance must still be checked and validated against datasheets and actual design conditions.
