The **ESSM-2-2-75** is a high-performance **High-Pass Filter (HPF)** manufactured by Mini-Circuits. It is designed in a surface-mount (SMT) package, specifically intended for high-frequency RF and microwave applications. --- ### ## Technical Specifications Below are the primary electronic characteristics of the ESSM-2-2-75: | Parameter | Value / Range | Unit | | :--- | :--- | :--- | | **Passband** | 2200 to 7500 | MHz | | **Stopband (Rejection)** | DC to 1350 | MHz | | **Insertion Loss (Passband)** | 1.5 (Typical) | dB | | **Stopband Rejection** | 20 (Minimum) | dB | | **VSWR (Typical)** | 1.6:1 | Ratio | | **Input Power (Max)** | 7 | Watts | | **Operating Temperature** | -40 to +85 | °C | --- ### ### Key Electronic Features 1. **High-Pass Architecture:** This component is designed to allow high-frequency signals (above 2200 MHz) to pass with minimal loss while significantly attenuating (blocking) lower frequencies. 2. **Wide Passband:** It covers a broad spectrum from S-band to C-band, making it versatile for wideband communication systems. 3. **Power Handling:** Capable of handling up to 7 Watts of continuous wave (CW) power, which is relatively high for a surface-mount filter of this size. 4. **Impedance Matching:** Standardized to **50 Ohms**, ensuring compatibility with most RF systems without requiring complex matching networks. --- ### ### Component Construction & Design The ESSM series utilizes specialized materials and multilayer construction to achieve high performance in a small footprint: * **Package Type:** Case Style DQ1225. It is a tiny, leadless surface-mount component. * **Substrate:** Typically utilizes high-Q ceramic or laminate materials to ensure low insertion loss. * **Shielding:** The design is inherently shielded to minimize electromagnetic interference (EMI) with neighboring components on the PCB. --- ### ### Typical Applications * **Electronic Warfare (EW):** Used to filter out low-frequency interference or jamming signals. * **Satellite Communications:** Protecting sensitive receivers from high-power low-frequency transmitters. * **Test and Measurement:** Used in signal generators and analyzers to clean up harmonic distortion. * **Radar Systems:** Filtering noise in X-band or C-band radar front-ends.
