Overview

The ADL5902 is a TruPwr mean-responding rms detector capable of measuring RF signals from 50 MHz to 9 GHz with high precision. It provides a linear-in-decibels output over a 65 dB dynamic range, from -62 dBm to 3 dBm, regardless of the signal waveform or modulation scheme. This device is particularly effective for complex signals like CDMA, W-CDMA, and WiMAX due to its waveform-independent conversion.

Why Choose This Part

The ADL5902 offers exceptional temperature stability of less than +/-0.3 dB and a transfer function ripple under +/-0.1 dB, ensuring high measurement accuracy across environmental changes. Its single-ended input design eliminates the need for external baluns or complex input matching, simplifying the RF front-end design and reducing PCB footprint.

Applications

Base Station Power Monitoring
Accurate transmitter output power measurement for cellular standards including GSM, CDMA, and W-CDMA.
WiMAX and Wi-Fi Transmitters
Providing precise power control for broadband wireless access systems operating up to 9 GHz.
Point-to-Point Microwave Links
Monitoring signal integrity and power levels in high-frequency microwave backhaul equipment.
RF Instrumentation
Integration into portable and bench-top RF power meters requiring high dynamic range and temperature stability.

Getting Started

Designers should utilize the ADL5902-EVALZ evaluation board to characterize the device's performance across various frequency bands. When designing the PCB, ensure the 16-LFCSP package's exposed pad is soldered to a low-impedance thermal and electrical ground plane to maintain measurement sensitivity and stability.
