The **CLA0930003JBEG** is a high-performance, low-profile **Multi-Layer Ceramic Chip Antenna (MLCC Antenna)** manufactured by **Inpaq Technology**. It is specifically designed for integration into mobile and compact wireless devices. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. General Specifications The CLA series utilizes Low Temperature Co-fired Ceramic (LTCC) technology to achieve high stability and efficiency in a surface-mount package. | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Inpaq Technology | | **Frequency Range** | 2.4 GHz - 2.5 GHz (ISM Band) | | **Package Size** | 9.0 x 3.0 x 1.1 mm | | **Mounting Type** | Surface Mount (SMD) | | **Impedance** | 50 $\Omega$ | | **Polarization** | Linear | --- ### 2. Electronic Performance Characteristics This part is optimized for Bluetooth, Wi-Fi, and ZigBee applications. Its performance is highly dependent on the Ground Plane design of the PCB it is mounted on. * **Bandwidth:** Typically covers the 2400MHz to 2500MHz spectrum. * **Peak Gain:** Generally ranges between **2.0 dBi to 3.5 dBi**, depending on the PCB layout and clearance zones. * **Efficiency:** High radiation efficiency (usually >70%) due to the ceramic material's low dielectric loss. * **VSWR:** Voltage Standing Wave Ratio is typically **< 2.0** at the resonant frequency. --- ### 3. Key Design Requirements Because this is a chip antenna, its electronic behavior is shaped by its physical environment: 1. **Clearance Zone:** The antenna requires a "keep-out" area (copper-free zone) on all layers of the PCB directly beneath and surrounding the part to prevent signal interference and detuning. 2. **Matching Network:** To ensure a perfect 50 Ohm match, a Pi-matching circuit (Shunt-Series-Shunt components) is usually required between the RF transceiver and the antenna. 3. **Feeding Point:** The signal is fed into one end of the ceramic body, while the other pads are used for mechanical stability or frequency tuning. --- ### 4. Applications The CLA0930003JBEG is commonly found in the following electronic devices: * **IoT Devices:** Smart home sensors and controllers. * **Wearables:** Fitness trackers and smartwatches. * **Audio:** Bluetooth headsets and wireless speakers. * **Computing:** Wi-Fi dongles and compact wireless modules. ---
