TFM.112A
Overview
The TFM.112A is a high-performance GNSS front-end module designed to support multi-band reception including L1, L2, and L-band frequencies. It integrates a two-stage Low Noise Amplifier (LNA) and SAW filters into a compact 34-SMD surface-mount package to provide superior signal integrity for high-precision positioning systems.
Why Choose This Part
The module features a two-stage LNA architecture that delivers high gain and a low noise figure of 3.5 nV/rtHz, ensuring stable performance across a wide 1.8V to 5.5V supply range. Its integrated SAW filters simplify RF front-end design by providing excellent out-of-band rejection in a small 18mm x 20mm footprint.
Applications
Key Specifications
Getting Started
Integration requires a 1.8V to 5.5V DC supply, with typical power consumption around 7.5-9.0mA at 1.8V. Engineers should ensure proper impedance matching on the RF input and output traces to maintain signal integrity for the 1.227GHz to 1.602GHz frequency range.
