TFM.100A

Overview

The TFM.100A is a highly integrated GNSS RF front-end module designed for multi-band satellite navigation reception across L1, L2, and L5 frequencies. It combines high-performance LNAs and specialized pre-filters into a single 34-pin SMD package to simplify the RF signal chain between the antenna and the receiver. This module provides significant gain and out-of-band rejection for applications requiring high precision and immunity to interference.

Why Choose This Part

The TFM.100A features a dual-stage LNA architecture providing over 25 dB of gain with a noise figure under 3.25 dB, ensuring high signal sensitivity. Its integrated pre-filters deliver exceptional out-of-band rejection to protect the GNSS receiver from neighboring signal interference. The module simplifies design by including impedance matching in a low-profile 18x20mm package, significantly reducing PCB routing complexity and development time.

Applications

Getting Started

To evaluate this module, ensure your PCB layout follows the recommended 50-ohm microstrip trace guidelines and provides adequate ground stitching for thermal and RF performance. The module operates on a wide input voltage range of 1.8V to 5.5V, making it compatible with most low-power GNSS chipsets and standard 3.3V systems. Taoglas offers evaluation boards that can be connected directly to GNSS receivers via SMA connectors for rapid prototyping.
