The TFM.100B from Taoglas is an L1/L5 Band GNSS Front-End Module for high-precision applications. It consists of two fully-integrated cascaded low noise amplifiers (LNA) + pre-filters (SAW/LNA/SAW/LNA topology) in the signal path to prevent unwanted out-of-band interference from overdriving the GNSS LNAs or receiver. The SAW filters have been carefully selected and placed to provide excellent out-of-band rejection while also maintaining a low noise figure. It has the required additional RF circuits in modular form, allowing the designer to simply place the TFM.100B between their GNSS antenna and GNSS receiver.
This FEM provides more than 25 dB of gain with a noise figure of less than 3 dB and operates at a frequency range of 1166 to 1610 MHz. It is available in a surface-mount package that measures 20 x 18 mm and requires a DC supply from 1.8 to 5.5 V. This single-package solution combines impedance matching, filter efficiency and low noise design for easy, drop-in use with any antenna or GNSS receiver.
