High-performance RF detector IC from Analog Devices Inc designed for precision signal measurement and control applications.

• Demodulating Logarithmic Amplifier: Accurately converts RF input signals to decibel-scaled output using progressive compression technique with detector cells in each amplifier stage.
• Wide Frequency Operation: Maintains accurate log conformance from 1 MHz to 8 GHz, usable up to 10 GHz.
• Large Dynamic Range: 40 dB input dynamic range (relative to 50 Ω) with less than ±1 dB error.
• Fast Response: 8 ns/10 ns fall/rise time enables detection of RF bursts exceeding 50 MHz pulse rate.
• Temperature Stable: Excellent logarithmic intercept stability across varying ambient temperatures.
• Dual-mode Operation: Supports both measurement mode (linear-in-dB output) and controller mode (power amplifier control voltage).
• Low-noise Output: Optimized for controller applications with minimized wide-band noise.
• Low Power Consumption: Operates from 3.0V to 5.5V supply with 22mA typical current (200μA when disabled).

• RF Transmitter PA Control: Set-point control and level monitoring for stable power amplifier operation.
• Radiolink Transmitter Power Monitoring: Ensures transmission power compliance and detects power-related faults.
• RSSI Measurement: Signal strength measurement in base stations, WLANs, WiMAX, and radar systems.
• RF Burst Detection: Fast detection of RF pulses in radar systems and short-burst communications.
