AD8315-EVAL屬于開發(fā)板套件編程器的射頻評(píng)估開發(fā)套件開發(fā)板。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD8315-EVAL射頻評(píng)估和開發(fā)套件，開發(fā)板本系列中的產(chǎn)品適用于在已知實(shí)施環(huán)境中，提供能訪問射頻相關(guān)器件的功能或者有助于訪問該功能。所含的焦點(diǎn)產(chǎn)品范圍從射頻信號(hào)鏈元器件（如放大器和檢測器）到模塊化收發(fā)器，以及不直接包含焦點(diǎn)產(chǎn)品的適配器硬件，但此類硬件可供方便地訪問用戶單獨(dú)提供的特定射頻產(chǎn)品或系列。

GENERAL DESCRIPTION

The AD8315 is a complete low cost subsystem for the precise control of RF power amplifiers operating in the frequency range 0.1 GHz to 2.5 GHz and over a typical dynamic range of 50 dB.

It is intended for use in cellular handsets and other battery operated wireless devices. The log amp technique provides a much wider measurement range and better accuracy than controllers using diode detectors. In particular, its temperature stability is excellent over a specified range of ?30°C to +85°C.

FEATURES

Complete RF detector/controller function

>50 dB range at 0.9 GHz (?49 dBm to +2 dBm, re 50 Ω)

Accurate scaling from 0.1 GHz to 2.5 GHz

Temperature-stable linear-in-dB response

Log slope of 23 mV/dB, intercept at ?60 dBm at 0.9 GHz

True integration function in control loop

Low power: 20 mW at 2.7 V, 38 mW at 5 V

Power-down to 10.8 μW

APPLICATIONS

Single, dual, and triple band mobile handset (GSM, DCS, EDGE)

Transmitter power control
