The **ADE-R272MH+** is a high-performance, surface-mount frequency mixer manufactured by **Mini-Circuits**. It is designed for frequency up-conversion and down-conversion in various RF systems. --- ## 1. Key Specifications The following table outlines the primary electrical characteristics of the ADE-R272MH+: | Parameter | Specification | | :--- | :--- | | **RF Frequency Range** | 1000 - 2700 MHz | | **LO Frequency Range** | 1000 - 2700 MHz | | **IF Frequency Range** | DC - 800 MHz | | **LO Power Level** | +13 dBm (Level 13) | | **Conversion Loss** | 6.5 dB (Typical) | | **Isolation (LO-RF)** | 32 dB (Typical) | | **Isolation (LO-IF)** | 27 dB (Typical) | | **Package Type** | CD542 (Surface Mount) | --- ## 2. Technical Features ### A. Double Balanced Design This part utilizes a **double-balanced** architecture. This provides excellent isolation between the LO (Local Oscillator), RF, and IF ports, reducing the leakage of signals and minimizing intermodulation distortion. ### B. High IP3 The "MH" designation typically refers to a **Medium-High** power rating. With a required LO power of +13 dBm, this mixer offers a high **Input Third-Order Intercept Point (IIP3)**, making it suitable for environments with strong interfering signals. ### C. Wideband Performance It covers the **L-Band** and portions of the **S-Band**, making it versatile for modern communication standards including cellular, GPS, and ISM bands. --- ## 3. Pin Configuration The ADE-R272MH+ is housed in a small 6-lead plastic case. The typical pinout is as follows: 1. **LO:** Local Oscillator Input. 2. **RF:** Radio Frequency Input/Output. 3. **IF:** Intermediate Frequency Output/Input. 4. **GND:** Ground (Multiple pins are grounded for thermal and signal integrity). --- ## 4. Common Applications * **Cellular Infrastructure:** Used in base stations for signal processing. * **PCN/PCS:** Personal Communications Service networks. * **WLAN/WiMAX:** Wireless networking equipment. * **Satellite Communications:** Down-converting satellite signals to manageable IF ranges. ---
