MAX4003 Datasheet 100mhz To 2500mhz / 45db Rf Detector

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2620; Rev 1; 3/03 100MHz to 2500MHz, 45dB RF Detector in a.

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 measurements.

This logarithmic amplifier provides much wider measurement range and superior accuracy than typical diode-based detectors.

Key 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 package (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. o Complete RF Detector o Frequency Range from 100MHz to 2500MHz o Input Range of -58dBV to -13dBV (-45dBm to 0dBm into 50Ω) o Fast Response: 70ns in 10dB Steps o Low-C.
