PRO-OB-430
Overview
The PRO-OB-430 is a high-performance stamped metal surface mount antenna designed specifically for GNSS applications. It supports major satellite constellations including GPS and GLONASS within a frequency range of 1.575GHz to 1.602GHz. Its compact 12.5mm by 12.43mm footprint and low profile of 3.33mm make it ideal for space-constrained mobile devices.
Why Choose This Part
The antenna offers a high efficiency of over 42 percent and a peak gain of 0.7 dBi in a rugged stamped metal form factor. It features a long 10-year shelf life and is designed for automated SMD assembly with standard solder termination. The wide bandwidth of 42MHz ensures stable performance across both GPS and GLONASS bands.
Applications
Key Specifications
Getting Started
Integration requires a dedicated ground plane as specified in the datasheet to ensure proper impedance matching and radiation patterns. Engineers should follow the recommended landing pattern for the 4-pin SMD package and keep the keep-out area clear of other metallic components. Performance can be validated using a network analyzer to verify the -10dB return loss at the target center frequency.
