RF Signal Generators

RF (Radio Frequency) signal generators are critical electronic components that generate repeating electronic signals at particular frequencies within the radio frequency range (typically from a few kHz to several GHz). These signals are then utilised for a wide variety of testing, measurement, and development purposes in electronic and telecommunication applications.   

How Do RF Signal Generators Function?

RF signal generators use numerous methods to produce signals, such as:

  • Oscillators: Produce a basic sinusoidal waveform at a specific frequency.
  • Frequency Synthesisers: Use phase-locked loops (PLLs) to generate highly precise and stable frequencies.
  • Modulators: Impose information onto the carrier signal by varying its amplitude (AM), frequency (FM), or phase (PM).

Unique Features and Benefits of Using Our Innovative RF Signal Generators

  • Frequency Range: The range of frequencies the generator can produce.   
  • Output Power: The strength of the generated signal.   
  • Modulation Capabilities: The types of modulation the generator can use (AM, FM, PM, pulse modulation, etc.).   
  • Signal Purity: The quality of the produced signal, such as factors like harmonic distortion, phase noise, and spurious signals.
  • Accuracy & Stability: How precisely the generator can produce the desired frequency and output power.

Where Can You Use RF Signal Generators?

  • Testing Receivers: Assessing the performance of radio receivers, such as sensitivity, selectivity, and interference rejection.
  • Testing Transmitters: Measuring the output power, frequency accuracy, and modulation characteristics of radio transmitters.
  • Component Testing: Characterising the functionality of RF components, including amplifiers, filters, and mixers.
  • Wireless Communication System Development: Simulating real-world signals for testing and developing wireless communication modules.
  • Radar & Electronic Warfare: Producing radar signals and simulating electronic warfare scenarios.

Summary

RF signal generators are integral instruments perfect for engineers and technicians working with RF and microwave circuits and systems. They offer the necessary signals for testing, characterising, and developing various electronic components and communication systems.
