产品信息
MAX4003EUA+T
100MHz to 2500MHz, 45dB RF Detector in a UCSP
射频检测器 100-2500MHz 45dB 射频检测器
General Description
The MAX4003EUA+T 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. Excellent temperature stability is achieved over the full operating range of -40°C to +85°C.
Features MAX4003EUA+T
♦ Complete RF Detector
♦ Frequency Range from 100MHz to 2500MHz
♦ Input Range of -58dBV to -13dBV (-45dBm to 0dBm into 50Ω)
♦ Fast Response: 70ns in 10dB Steps
♦ Low-Current Consumption: 5.9mA at VCC = 3.0V
♦ 13μA (typ) Shutdown Current
♦ Available in 8-Bump UCSP or 8-Pin μMAX and Thin QFN Packages
Applications MAX4003EUA+T
Cellular Handsets (TDMA, CDMA, GPRS, GSM)
TSSI for Wireless Terminal Devices
Transmitter Power Measurement and Control
RSSI for Fiber Modules
