HMC1010LP4E is a RF power detector produced by Hittite Microwave. This application guide is a supplement to its data sheet, which introduces the basic principle, typical application connection method, slope and cutoff point, error calibration and other content of the product.
This document is a Chinese translation and supplement of the "Application Information" section of the HMC1010LP4E data sheet from Hittite Microwave. It provides an overview of the RMS power detector’s operation, typical conversion slope, and how to configure the device for various RF input scenarios.
The note describes the differential and single‑ended input interfaces, required DC‑blocking capacitors, and how the SCI1‑SCI4 control pins adjust the integration time, affecting transient response and detection accuracy. It also covers methods for calibrating conversion slope and cutoff point, and includes example circuits for 900 MHz, 1900 MHz, and 2100 MHz applications. This manual is written in Chinese.
| Typical conversion slope | 36.6 mV/dB at 900 MHz |
|---|---|
| Differential input impedance | 150 Ω |
| SCI control pins | SCI1‑SCI4 |
The typical conversion slope is 36.6 mV per dB at 900 MHz.
Yes, the device accepts either single‑ended or differential RF input signals.
