The **PE2CP1045** is a high-performance, ultra-wideband **90-degree Hybrid Coupler** manufactured by Pasternack. This electronic component is primarily used in RF (Radio Frequency) and microwave systems to split or combine signals with a specific phase relationship. --- ### 1. Technical Specifications The following table summarizes the core electronic characteristics of the PE2CP1045: | Parameter | Specification | | :--- | :--- | | **Frequency Range** | 2 GHz to 18 GHz | | **Impedance** | 50 Ohms | | **Coupling** | 3 dB (Nominal) | | **Phase Balance** | ± 5 Degrees | | **Insertion Loss** | 1.3 dB (Maximum) | | **Isolation** | 17 dB (Minimum) | | **Input Power (CW)** | 100 Watts | | **Connector Type** | SMA Female | --- ### 2. Functional Roles As a 90-degree hybrid (also known as a **Quadrature Hybrid**), the PE2CP1045 performs several critical functions within a circuit: * **Signal Splitting:** It takes an input signal and divides it into two output signals of equal power, but with a **90° phase shift** between them. * **Signal Combining:** It can combine two signals while maintaining high isolation between the input ports, which is essential for protecting sensitive components. * **Reflected Power Management:** Due to its phase properties, it is often used in balanced amplifiers to redirect reflected power away from the source and into a dummy load. --- ### 3. Key Electronic Features * **Ultra-Wideband Performance:** Operating from 2 GHz to 18 GHz makes it versatile for applications ranging from S-band radar to Ku-band satellite communications. * **High Power Handling:** Rated for **100 Watts CW**, it is suitable for power amplification stages. * **Rugged Construction:** Typically housed in a passivated stainless steel or aluminum enclosure to ensure EMI shielding and durability in harsh environments. --- ### 4. Typical Applications 1. **Phase Shifters:** Creating variable phase shifts in antenna arrays. 2. **IQ Modulators/Demodulators:** Separating signals into In-phase (I) and Quadrature (Q) components. 3. **Balanced Amplifiers:** Improving VSWR (Voltage Standing Wave Ratio) by combining two identical amplifiers. 4. **Test and Measurement:** Tapping into signals for monitoring without significantly disrupting the main signal path. ---
