Introduction
ADL5513ACPZ-R7 High-Performance Logarithmic Detector/Controller
A high-performance, broadband logarithmic detector/controller manufactured by Analog Devices, designed for precision RF and microwave power measurement applications.
Key Functions
Broadband Logarithmic Detection
Operates over a wide frequency spectrum from DC to 10 GHz, providing logarithmic response to input RF/microwave power levels
Converts input power into proportional DC voltage output with excellent logarithmic linearity
High Dynamic Range Measurement
Offers typical dynamic range of 60 dB (up to 70 dB under optimized conditions)
Enables accurate power detection from low-level signals to high-power inputs
Temperature Compensation
Incorporates on-chip temperature compensation circuit
Minimizes impact of ambient temperature variations on detection accuracy
Ensures stable performance across operating temperature range of -40°C to +85°C
Flexible Output Configuration
Provides both logarithmic DC voltage output and threshold comparator output
Supports power level monitoring and over-power/under-power protection modes
Low Power Consumption
Features low quiescent current for energy-efficient operation
Ideal for battery-powered or low-power RF systems
Typical Applications
RF/Microwave Power Monitoring
Transmitter output power monitoring in wireless communication systems (4G/5G base stations, satellite communication transceivers)
Power level verification in radar systems and test instrumentation
Automatic Gain Control (AGC) Systems
Implementing closed-loop gain control in RF receivers
Ensuring stable signal levels and preventing saturation of subsequent stages
Optimizing gain adjustment in broadband amplifiers and transceivers
Over-Power Protection
Protecting sensitive RF components (mixers, amplifiers) from excessive input power
Triggering protective circuits in communication and radar systems
Industrial RF equipment and medical devices (RF ablation systems)
Test and Measurement Equipment
