PCTEL 3961D Low Noise Embedded GPS Antenna
The PCTEL 3961D low noise embedded GPS antenna features a tuned custom ceramic patch element that minimizes detuning effects caused by adjacent objects. It also features ESD circuit protection, an innovative LNA (Low Noise Amplifier) and high rejection SAW (Surface Acoustic Wave).
Description
Overview
The PCTEL 3961D embedded GPS antenna has one of the industry’s lowest noise figures. It features a tuned custom ceramic patch element that minimizes detuning effects caused by adjacent objects. The 3961Da ntenna also features ESD circuit protection, an innovative LNA (low noise amplifier) and a high rejection SAW filter which enable these antennas to provide a consistent, clear signal while minimizing loss-of-lock even when GPS conditions are less than ideal.
The 3961D comes with a 45.2 mm diameter mini ground plane.
Features
- Low noise figure — 0.5 dB
- Superior filtering – Via an innovative two-stage low noise amplifier and a dual SAW high rejection filter
- Consistent, clear signal reception – Minimal loss-of-lock in high-RF fields
- Low current draw — 7.5 mA @ 3.3 VDC; 15 KV ESD circuit protection
- Easy installation – Comes with internal ground plane
Applications
- Embedded implementations
