The **SES-2AD-R** is a high-performance electronic component typically used in telecommunications and RF (Radio Frequency) signal processing. It is a **2-way 90° Power Splitter/Combiner** designed for surface-mount applications. --- ### ## Technical Specifications The following table outlines the primary electrical characteristics of the SES-2AD-R: | Parameter | Typical Value | Unit | | :--- | :--- | :--- | | **Frequency Range** | 1000 - 2000 | MHz | | **Insertion Loss** | 0.4 - 0.7 | dB (above 3dB) | | **Isolation** | 18 - 25 | dB | | **Phase Unbalance** | 1.0 - 3.0 | Degrees | | **Amplitude Unbalance** | 0.5 - 1.0 | dB | | **Input VSWR** | 1.2:1 | Ratio | --- ### ### Key Electronic Features 1. **90° Quadrature Phase:** Unlike standard 0° splitters, this part shifts the phase of the second output port by 90 degrees relative to the first. This is critical for I/Q modulation and image-reject mixers. 2. **Low Insertion Loss:** The device is engineered to minimize power dissipation, ensuring high signal integrity across the L-band frequency range. 3. **Excellent Isolation:** It maintains high separation between the two output ports, preventing signal leakage or feedback into the source. 4. **Compact Surface Mount (SMT):** Designed for automated assembly lines, typically housed in a small, shielded case to prevent Electromagnetic Interference (EMI). --- ### ### Typical Applications * **Modulators/Demodulators:** Used to create the I (In-phase) and Q (Quadrature) components of a signal. * **Balanced Amplifiers:** Splitting a signal to two amplifiers and recombining them to improve stability and power. * **Phased Array Antennas:** Providing the necessary phase shifts for beamsteering. * **Signal Processing:** Frequency translation and image rejection in receivers. --- ### ### Schematic Representation In a circuit, the pinout typically follows a specific configuration to ensure impedance matching (usually 50 Ohms): ```text [ Input ] (Pin 1) | -------|------- | | [Output 1] [Output 2] (0 deg) (90 deg) (Pin 2) (Pin 5) ```
