The **LPD-32P4-R/Q** is a high-performance power divider (splitter) manufactured by **Mini-Circuits**. It is designed specifically for radio frequency (RF) and microwave applications, primarily used to split an input signal into 32 equal output phases and amplitudes. --- ### 1. Key Technical Specifications The following table summarizes the core electronic characteristics of the device: | Parameter | Specification | | :--- | :--- | | **Frequency Range** | 700 to 2700 MHz | | **Insertion Loss** | 1.8 dB (above theoretical 15.1 dB split) | | **Isolation** | 20 dB (Typical) | | **Phase Unbalance** | 10.0 Degrees (Max) | | **Amplitude Unbalance** | 1.2 dB (Max) | | **VSWR (Input/Output)** | 1.3:1 / 1.2:1 | | **Connector Type** | SMA-Female | --- ### 2. Electronic Architecture The "LPD" series typically utilizes a **Microstrip/Stripline** corporate-feed network. This involves several stages of 2-way power splitters (Wilkinson type) arranged in a tree structure to reach the 32-way output. #### Core Components: * **Impedance Matching Networks:** Ensure that the input and output ports maintain a 50-ohm characteristic impedance to prevent signal reflections. * **Isolation Resistors:** Internal resistors are used to prevent signals from one output port from leaking into another, which is critical for system stability. * **Low-Loss Dielectrics:** The internal PC board uses high-frequency laminates to minimize signal attenuation over the 700-2700 MHz band. --- ### 3. Mechanical & Environmental Features The "R/Q" suffix often denotes specific ruggedization or quality standards for the housing. * **Housing:** Usually a rugged aluminum alloy case with a chemical film or nickel plating for EMI/RFI shielding. * **Operating Temperature:** Typically rated from -40°C to +85°C. * **Power Handling:** Designed to handle moderate RF input power (usually around 10-30 Watts as a splitter, though much less when used as a combiner). --- ### 4. Common Applications Due to its wide frequency range (covering cellular, Wi-Fi, and LTE bands), it is used in: 1. **DAS (Distributed Antenna Systems):** Splitting a single base station signal to 32 different antennas inside a building. 2. **Test Labs:** Simultaneous testing of 32 mobile devices or receivers. 3. **Satellite Communications:** Signal distribution in ground stations.
