Description
Overview
The 3961D-HR high rejection embedded GPS antenna provides 25 dB gain, superior out-of-band rejection performance and is the optimum choice for embedded GPS tracking and timing applications with high RF fields. It features a precision tuned custom ceramic patch element for maximum signal reception, 15KV ESD circuit protection, a multi-stage LNA circuit and dual high rejection SAW filters. This enables the 3961D-HR to provide a reliable and clear GPS signal while minimizing loss-of-lock, even when conditions are less than ideal.
The 3961D-HR comes with a 45.2 mm diameter mini ground plane.
