Product Description

ADI chips MAX4003EUA+T 100MHz to 2500MHz, 45dB RF Detector in a UCSP

General Description

The MAX4003 low-cost, low-power logarithmic amplifier

is designed to detect the power levels of RF power

amplifiers (PAs) operating from 100MHz to 2500MHz. A

typical dynamic range of 45dB makes this logarithmic

amplifier useful in a variety of wireless applications

including cellular handset PA control, TSSI for wireless

terminal devices, and other transmitter power measure-

ments. This logarithmic amplifier provides much wider

measurement range and superior accuracy than typical

diode-based detectors. Excellent temperature stability is

achieved over the full operating range of -40°C to +85°C.

The MAX4003 logarithmic amplifier is a voltage-mea-

suring device with a typical signal range of -58dBV to

-13dBV. The input signal is internally AC-coupled by an

on-chip 5pF capacitor in series with a 2kΩ resistance.

This highpass coupling, with a corner at 16MHz, sets

the lowest operating frequency and allows the input

signal source to be DC grounded. The MAX4003 also

features a power-on delay, which holds the detector

output (OUT) low for approximately 5µs to ensure

glitchless controller output.

The MAX4003 is available in an 8-bump chip-scale pack-

age (UCSP™), an 8-pin µMAX package, and an 8-pin thin

QFN package. The device consumes 5.9mA with a 3.0V

supply and only 13µA when the device is in shutdown.

Applications

Cellular Handsets (TDMA, CDMA, GPRS, GSM)

TSSI for Wireless Terminal Devices

Transmitter Power Measurement and Control

RSSI for Fiber Modules
