Product Introduction

  1. Dual-Band Precision: Covers GPS L1 (1575MHz) and GLONASS (1592-1608MHz) frequencies with RHCP polarization, ensuring reliable satellite signal reception for accurate positioning.

  2. Robust Environmental Tolerance: Operates in extreme temperatures (-40℃ to +85℃) and passes rigorous tests (humidity, vibration, thermal cycling) for reliability in harsh conditions.

  3. Compact & Durable Design: Miniature dimensions (12.1mm ±0.2) and RoHS-compliant construction, ideal for space-constrained applications like IoT devices and wearables.

  4. Stable Electrical Performance: Low return loss (-11dB max), 50Ω impedance, and ±2MHz center frequency stability ensure consistent signal integrity.

  5. Easy Integration: Compatible with standard soldering processes (350℃ tolerance) and includes protective packaging for safe transportation and storage.

Application scenarios

  • Automotive navigation systems

  • Fleet tracking and telematics

  • IoT asset tracking devices

  • Outdoor handheld GNSS receivers

  • Industrial drones and robotics
