The **FMANMOB1006-RSP** is a high-performance, compact **GPS/GNSS active internal patch antenna** manufactured by Pasternack (or its subsidiaries/partners like Fairview Microwave). It is designed specifically for mobile and portable devices requiring high-precision positioning. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Frequency Range** | 1575.42 MHz (GPS L1 Band) | | **Gain (Patch)** | 2.0 dBi (Typical) | | **LNA Gain** | 28 dB (Integrated Low Noise Amplifier) | | **Noise Figure** | 1.5 dB (Typical) | | **Voltage Supply** | 2.2V to 5.0V DC | | **Current Consumption** | 5mA to 15mA | | **Output Impedance** | 50 Ohms | | **Connector Type** | SMA Male Plug | | **Cable Type** | RG174 or equivalent (usually 3 meters) | --- ### 2. Functional Components The "Electronic Parts" within this assembly consist of three main stages: #### A. The Ceramic Patch Element This is the square "tan" block visible on the unit. It acts as the transducer that converts electromagnetic waves from satellites into electrical signals. It is tuned specifically to the **L1 frequency**. #### B. Integrated Low Noise Amplifier (LNA) Since GPS signals are extremely weak by the time they reach Earth, this module contains an internal LNA circuit. * **Purpose:** It boosts the signal-to-noise ratio (SNR) before the signal travels down the cable to the receiver. * **Powering:** It is "active," meaning it requires DC power sent from the GPS receiver through the coaxial cable (Phantom Power). #### C. Surface Acoustic Wave (SAW) Filter Integrated within the circuitry is a SAW filter designed to reject out-of-band interference (such as cell phone signals or Wi-Fi) that could saturate the LNA. --- ### 3. Application Use-Cases * **Fleet Management:** Real-time tracking of logistics vehicles. * **Portable Devices:** Handheld GPS units requiring internal integration. * **IoT Gateways:** Providing location data to industrial internet-of-things nodes. * **Autonomous Systems:** Basic positioning for UAVs or ground robots. --- ### 4. Installation Considerations * **Ground Plane:** This antenna usually performs best when mounted on or near a metal ground plane to stabilize the radiation pattern. * **Orientation:** The ceramic patch must face the sky (zenith) for optimal satellite acquisition. * **ESD Protection:** As an active electronic component, it is sensitive to Electrostatic Discharge during handling and installation.
