ADL5500: 100 MHz至6 GHz TruPwr™检波器
ADL5500是一款均值响应功率检波器，适用于100 MHz至6 GHz的高频接收机和发射机信号链。它易于使用，仅需一个2.7 V至5.5 V单电源和一个电源去耦电容便可工作。输入在内部交流耦合，标称输入阻抗为50 Ω。输出为线性响应直流电压，900 MHz时的转换增益为6.4 V/V均方根值。输出上的1 kΩ片内串联电阻与一个外部分流电容配合，可提供低通滤波器响应，进而减少直流输出电压中的残留纹波。ADL5500主要用于简单和复合波形的真功率测量，特别适合测量高波峰因素（高峰值-均方根比）信号，如基于CDMA2000、W-CDMA、QPSK/QAM的OFDM波形等。ADL5500具有出色的温度稳定性，整个温度范围内的测量误差接近于0 dB。该器件具有高精度范围，在900 MHz时以+3 dBm为中心，在-40°C至+85°C温度范围内误差为±0.1 dB。它提供4引脚、1.0 mm × 1.0 mm晶圆级芯片规模封装，采用专有的高fT硅双极性工艺制造。
The ADL5500 is a mean-responding power detector for use in high frequency receiver and transmitter signal chains from 100 MHz to 6 GHz. It is easy to apply, requiring only a single supply between 2.7 V and 5.5 V and a power supply decoupling capacitor. The input is internally ac-coupled and has a nominal input impedance of 50 Ω. The output is a linear-responding dc voltage with a conversion gain of 6.4 V/V rms at 900 MHz. The on-chip, 1 kΩ series resistance at the output combined with an external shunt capacitor creates a low-pass filter response that reduces the residual ripple in the dc output voltage.
The ADL5500 is intended for true power measurement of simple and complex waveforms. The device is particularly useful for measuring high crest factor (high peak-to-rms ratio) signals, such as CDMA2000, W-CDMA, and QPSK/QAM-based OFDM waveforms.The ADL5500 offers excellent temperature stability with near 0 dB measurement error across temperature. The high accuracy range, centered around +3 dBm at 900 MHz, offers ±0.1 dB error from -40°C to +85°C and is available in a 4-ball, 1.0 mm × 1.0 mm wafer-level chip scale package. It is fabricated on a proprietary high fT silicon bipolar process
