RF Detectors

RF detectors are used to convert RF signal strength into a proportional DC voltage. Commonly used for power measurement, signal presence detection, and automatic gain control (AGC).

• Types:
  • Logarithmic (Log Amp)
  • Linear (RMS or Envelope)
  • Peak Detector
• Key Parameters:
  • Frequency Range
  • Detection Range (Dynamic Range)
  • Response Time
  • Temperature Stability
  • Output Voltage Linearity
• Applications:
  • Transmitter Power Control
  • Receiver Signal Strength Indication (RSSI)
  • Wireless Infrastructure
  • Test & Measurement Equipment
