The **ADE-R30WLH** is a high-performance, double-balanced frequency mixer manufactured by Mini-Circuits. It is designed for signal processing applications where high dynamic range and low conversion loss are critical. --- ### 1. Key Technical Specifications The device is characterized by its wide frequency coverage and robust power handling capabilities. | Parameter | Specification | | :--- | :--- | | **RF/LO Frequency Range** | 1200 - 3000 MHz | | **IF Frequency Range** | DC - 1000 MHz | | **LO Drive Level** | +17 dBm (High Power) | | **Conversion Loss** | 6.5 dB (Typical) | | **Isolation (LO-RF)** | 32 dB (Typical) | | **Isolation (LO-IF)** | 27 dB (Typical) | | **Package Type** | CD542 (Surface Mount) | --- ### 2. Internal Components & Architecture The "R" in the part number often signifies a specific internal diode configuration or environmental ruggedness. * **Schottky Diode Quad:** The core of the mixer uses a ring of four matched Schottky diodes. The "LH" suffix indicates a **High Drive Level (+17 dBm)**, meaning the diodes have a higher barrier voltage, allowing the mixer to handle higher input signals without distorting (high IP3). * **Balun Transformers:** It contains two internal wideband ferrite transmission line transformers. These convert single-ended signals into balanced signals to drive the diode ring, ensuring high isolation between ports. * **Ceramic Substrate:** Built on a low-temperature co-fired ceramic (LTCC) or similar rugged substrate to ensure thermal stability across the -40°C to +85°C operating range. --- ### 3. Pin Configuration The ADE-R30WLH uses a 6-pin surface mount layout. | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | **LO** | Local Oscillator Input | | **2** | **GND** | Ground | | **3** | **RF** | Radio Frequency Input | | **4** | **IF** | Intermediate Frequency Output | | **5** | **GND** | Ground | | **6** | **GND** | Ground | --- ### 4. Typical Applications Due to its high LO power requirements, this part is ideal for environments with significant interference: * **Cellular Infrastructure:** Signal up/down conversion in base stations. * **Defense Systems:** Radar and electronic warfare receivers. * **ISM Band:** Industrial, scientific, and medical equipment operating near 2.4 GHz. ---
