## Overview of the ADE-R3GLH The **ADE-R3GLH** is a high-performance, surface-mount **Frequency Mixer** manufactured by Mini-Circuits. It is specifically designed for high-reliability applications, often used in telecommunications, radar systems, and defense electronics. ### 1. Key Technical Specifications The following table outlines the primary electronic characteristics of the component: | Parameter | Value / Range | Unit | | :--- | :--- | :--- | | **RF Frequency Range** | 100 - 3000 | MHz | | **LO Frequency Range** | 100 - 3000 | MHz | | **IF Frequency Range** | 10 - 700 | MHz | | **Conversion Loss** | 6.5 (Typical) | dB | | **LO Power Level** | +17 (Level 17) | dBm | | **LO-RF Isolation** | 35 (Typical) | dB | | **LO-IF Isolation** | 30 (Typical) | dB | | **IP3 (Input)** | 23 (Typical) | dBm | --- ### 2. Internal Electronic Architecture The ADE-R3GLH is a **Double Balanced Mixer**. Its internal circuitry consists of two main sections: 1. **Schottky Diode Quad:** The heart of the mixer is a ring of four matched diodes. Because this is a "Level 17" mixer, these diodes are chosen for their ability to handle high Local Oscillator (LO) power, which reduces intermodulation distortion. 2. **Transmission Line Transformers (Baluns):** It utilizes wideband ferrite-core transformers to balance the signals between the unbalanced ports (RF, LO, IF). These transformers ensure high isolation between ports, preventing the LO signal from leaking into the RF or IF paths. --- ### 3. Application and Usage Because this component is a **Level 17 mixer**, it is optimized for high linearity. Electronic engineers typically use it for: * **Frequency Up-conversion:** Translating a low-frequency IF signal to a higher RF frequency for transmission. * **Frequency Down-conversion:** Translating a high-frequency received RF signal down to a lower IF for processing. * **Defense Systems:** Used in electronic warfare (EW) and secure communication due to its wide bandwidth and rugged construction. --- ### 4. Physical and Environmental Features * **Package Type:** CD542 (Surface Mount). * **Lead Finish:** Gold over Nickel (indicated by the "G" in the part number), which provides excellent solderability and prevents oxidation. * **Hermeticity:** The "H" suffix often denotes a hermetically sealed or high-reliability ruggedized version, capable of operating in harsh environments (typically -40°C to +85°C). ---
