Overview
The APAE1575R1840AADB7-T is a passive ceramic patch GNSS antenna designed for L1 band reception. It operates at a center frequency of 1.5835 GHz with a maximum frequency of 1.57542 GHz. The component features a gain of 3 dBi and an input impedance of 50 Ohms. Physical dimensions are 18 mm in length, 18 mm in width, and 4 mm in height. It utilizes pin-type termination for PCB mounting and supports Right Hand Circular Polarization.
Feature Summary
- Compact ceramic patch design with low profile
- High gain performance for improved signal reception
- Pin-type termination for secure PCB integration
Applications
- Automotive navigation systems
- Marine buoys
- Surveying equipment
Procurement Notes
Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with required polarization and mounting specifications. Confirm RoHS compliance status and environmental operating temperature ranges prior to integration. Cross-reference the part number with authorized distributors to validate authenticity and current production status.
Selection Notes
Select this model when a compact 18x18mm footprint is required for L1 band GNSS applications. The 3 dBi gain offers a balance between size and performance for standard navigation tasks. Ensure the host PCB layout accommodates the 4mm height and pin-type connections for reliable mechanical and electrical attachment.
Part Context
This component belongs to the APAE series of GNSS antennas from Abracon. It is engineered specifically for GPS, GLONASS, Galileo, and Beidou signal reception. The design prioritizes space-constrained environments while maintaining robust RF performance through its ceramic construction and optimized patch geometry.
Replacement Considerations
Direct substitutes within the same series include APAE1575R1820ABDC1-T and APAE1575R1240ABDD1-T. Verify dimensional constraints and gain requirements before swapping, as these variants differ in physical size and RF performance characteristics.
