Surface mount GNSS front-end module covering L1 and L2 bands
The Taoglas TFM.100A is a surface-mount GNSS front-end which covers L1+B1+G1/L2 for dual-band high-precision applications. The module features a SAW/LNA/SAW/LNA topology in both the low and high band signal paths 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 low noise figure.
Many currently available dual-band GNSS receivers require additional RF circuits between the antenna and the receiver to properly set the overall system noise figure. This requires additional development time for an otherwise simple module integration. Many organizations don’t have the RF expertise to effectively design such a solution. The TFM.100A captures the required additional RF circuits in modular form, allowing the designer to simply place the TFM.100A between their GNSS antenna and GNSS receiver.
The TFM.100A offers > 25 dB gain across all applicable bands while maintaining a high P1dB of -24 dBm or better. Noise Figure is < 3.25 dB in the low bands and < 3.0 dB in the high bands. A wide input voltage of +1.8 to +5.5 VDC allows for easy integration in most GNSS systems.
Taoglas also offers the TFM.100B for L1+B1+G1/L5 applications.
