The **LPD-22MA-R** is a high-performance **2-Way Power Divider/Combiner** designed for radio frequency (RF) and microwave applications. It is typically manufactured by specialized RF component companies (like Lead-Power or similar microwave part suppliers). --- ## 1. Core Technical Specifications The following table highlights the primary electronic characteristics of the LPD-22MA-R: | Parameter | Specification | Units | | :--- | :--- | :--- | | **Frequency Range** | 2.0 – 22.0 | GHz | | **Insertion Loss** | ≤ 1.2 (excluding 3dB split) | dB | | **Isolation** | ≥ 18 | dB | | **Amplitude Balance** | ± 0.3 | dB | | **Phase Balance** | ± 4 | Degrees | | **VSWR (Input/Output)** | ≤ 1.5:1 | Ratio | | **Power Handling** | 20 (Forward) / 2 (Reverse) | Watts | | **Impedance** | 50 | Ohms | --- ## 2. Key Electronic Features ### A. Broadband Performance Unlike narrowband dividers, the "MA" series is designed for ultra-wideband operation, covering the S, C, X, and Ku bands (2-22 GHz). This makes it suitable for electronic warfare (EW), radar, and wideband communication systems. ### B. Power Symmetry The device maintains high **Amplitude and Phase Balance**. This ensures that when a signal is split, both output ports receive an equal amount of power with minimal timing (phase) offset, which is critical for antenna arrays. ### C. Low Insertion Loss Electronic efficiency is high due to the low insertion loss (1.2 dB above the theoretical 3 dB split). This minimizes heat dissipation and preserves signal integrity. --- ## 3. Physical & Interface Properties * **Connectors:** Usually equipped with **SMA-Female** or **2.92mm (K)** connectors to handle the high-frequency range up to 22 GHz. * **Housing:** Typically housed in a CNC-machined aluminum enclosure with conductive plating (e.g., Gold or Chem-film) to ensure electromagnetic interference (EMI) shielding. * **Circuit Topology:** Internally uses a **Wilkinson Power Divider** design, which utilizes internal resistors to provide high isolation between output ports. --- ## 4. Typical Applications 1. **Test & Measurement:** Splitting a source signal to both a Device Under Test (DUT) and a Spectrum Analyzer. 2. **Phased Array Antennas:** Distributing local oscillator (LO) signals. 3. **Signal Combining:** Using the device in reverse to combine two low-power signals into a single output.
