The LMH2110 is a 45-dB Logarithmic RMS power detector particularly suited for accurate power measurement of modulated RF signals that exhibit large peak-to-average ratios; that is, large variations of the signal envelope. Such signals are encountered in W-CDMA and LTE cell phones. The RMS measurement topology inherently ensures a modulation insensitive measurement.

The device has an RF frequency range from 50 MHz to 8 GHz. It provides an accurate, temperature and supply insensitive output voltage that relates linearly to the RF input power in dBm. The LMH2110 device has excellent conformance to a logarithmic response, enabling easy integration by using slope and intercept only, reducing calibration effort significantly. The device operates with a single supply from 2.7 V to 5 V. The LMH2110 has an RF power detection range from –40 dBm to 5 dBm and is ideally suited for use in combination with a directional coupler. Alternatively, a resistive divider can be used.

The device is active for EN = High; otherwise, it is in a low power-consumption shutdown mode. To save power and prevent discharge of an external filter capacitance, the output (OUT) is high-impedance during shutdown.

TIDA-00897 — 用于 WLAN 应用的高精度对数 RMS 功率检测器参考设计

动态发射功率控制对于在无线局域网 (WLAN) 中提高频谱效率和减少相邻信道干扰至关重要。此外，全球各地的监管机构都要求将发射功率限制在一定水平，以便减少对其他通信设备的干扰。在 WLAN 系统中控制发射功率的另一个好处是，可以通过降低功率放大器的电源电压来延长电池寿命。此参考设计展示了针对 WLAN 应用的闭环动态发射功率控制。尽管此特定设计实现的是 WLAN 发射功率控制，但对于其他无线技术（例如 LTE），也可使用类似的概念来实施功率控制方案。

发射功率控制的应用范围非常广泛：从移动手持设备到工业再到汽车应用均适用。例如，LMH2110 可用于汽车电子产品，从而满足 LTE 或 WiFi (...)
