Taoglas TFM Series Multiband GNSS Front End Modules

Taoglas TFM Series Multiband GNSS Front End Modules cover L1+B1+G1 / L1 / L2 / L5 for multi-band, multi-constellation high-precision applications. The TFM features a SAW / LNA / SAW / LNA topology in the signal path, preventing unwanted out-of-band interference from overdriving the GNSS LNAs or receivers. This GNSS front end captures the required additional RF circuits in modular form, allowing the user to place the TFM between the GNSS antenna and the GNSS receiver. The integrated pre-filters deliver excellent out-of-band rejection across multiple band configurations and neighboring interference to properly set noise figures. Taoglas TFM modules boast impedance matching, filter efficiency, and low-noise design for easy, drop-in use with any antenna or GNSS receiver.
