The **ACTE-532-R** is a high-performance, ultra-compact **GPS/GNSS Antenna Module** designed by Sparklan. It integrates a high-sensitivity patch antenna with a sophisticated Front-End circuit to provide reliable positioning in space-constrained electronic devices. --- ### 1. Key Electronic Specifications The module is built around a high-gain ceramic patch antenna and an integrated **Low Noise Amplifier (LNA)**. | Parameter | Specification | | :--- | :--- | | **Frequency Range** | 1575.42 MHz ± 1.023 MHz | | **Operating Voltage** | 3.0V - 5.0V DC | | **Current Consumption** | ~10mA to 15mA | | **Gain (Patch Antenna)** | 2.0 dBi (typical) | | **Output Impedance** | 50 Ohms | | **Connector Type** | Right-Angle MMCX or U.FL (Variable by sub-model) | --- ### 2. Functional Components The ACTE-532-R is more than just a piece of ceramic; it contains several critical electronic stages: * **Ceramic Patch Element:** A 13x13mm or 18x18mm square ceramic substrate that captures the electromagnetic waves from GPS satellites. * **SAW Filter (Surface Acoustic Wave):** This component acts as a gatekeeper, filtering out out-of-band interference from cellular (LTE) or WiFi signals to prevent receiver desensitization. * **Low Noise Amplifier (LNA):** Boosts the extremely weak satellite signals (often below -130 dBm) to a level that the GPS receiver chip can process. * **Impedance Matching Network:** A circuit consisting of inductors and capacitors (LC circuit) that ensures maximum power transfer between the antenna and the 50-ohm transmission line. --- ### 3. Implementation Details To use the ACTE-532-R in an electronic design, developers must consider the following: #### Pinout and Connectivity Most variants utilize a micro-coaxial cable. If integrating the raw module onto a PCB: 1. **VCC:** Power supply (must be clean/decoupled with a 0.1uF capacitor). 2. **GND:** A solid ground plane is required to act as a "Reflector" for the antenna element. 3. **RF_OUT:** The signal path leading to the GNSS receiver. #### Performance Features * **RHCP Polarization:** Right-Hand Circular Polarization matches the signal transmitted by GPS satellites. * **Compact Form Factor:** Designed for handheld trackers, dashcams, and UAVs. ---
