ADL5501: 50 MHz至6 GHz TruPwr检波器
ADL5501是一款均值响应功率检波器，适用于50 MHz至6 GHz的高频接收机和发射机信号链。它易于使用，仅需2.7 V至5.5 V单电源和一个电源去耦电容便可工作。输入为内部交流耦合，具有50 Ω标称输入阻抗。输出为线性响应直流电压，900 MHz时的转换增益为6.3 V/V均方根值。ADL5501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CDMA、CDMA2000、W-CDMA、QPSK/QAM的OFDM波形等。片内调制滤波器可以满足大多数波形的求平均值需要。输出端的100 Ω片内串联电阻与外部分流电容配合，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。对于更复杂的波形，可以利用FLTR引脚上的外部电容进行补充信号解调。ADL5501在30 dB范围内具有出色的温度稳定性；在整个温度范围及动态范围的上段，测量误差接近于0 dB。除温度稳定性外，ADL5501还具有出色的工艺稳定性，从而进一步降低了校准复杂度。ADL5501的工作温度范围为−40°C至+85°C，提供6引脚小型SC-70封装，采用专有的高fT硅双极性工艺制造。
The ADL5501 is a mean-responding power detector for use in high frequency receiver and transmitter signal chains from 50 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 6.3 V/V rms at 900 MHz.
The ADL5501 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 CDMA-, CDMA2000-, W-CDMA-, and QPSK-/QAM-based OFDM waveforms. The on-chip modulation filter provides adequate averaging for most waveforms.The on-chip, 100 Ω 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. For more complex waveforms, an external capacitor at the FLTR pin can be used for supplementary signal demodulation.
The ADL5501 offers excellent temperature stability across a 30 dB range and near 0 dB measurement error across temperature over the top portion of the dynamic range. In addition to its temperature stability, the ADL5501 offers low process variations that further reduce calibration complexity.The ADL5501 operates from −40°C to +85°C and is available in a small 6-lead SC-70 package. It is fabricated on a proprietary high fT silicon bipolar process.
