The TFM.110A from Taoglas is a Multiband GNSS Front-End Module that covers L1/L2/L5 bands for high-precision applications. It consists of two fully-integrated cascaded low noise amplifiers (LNA) and 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. When used between the device’s GNSS receiver and antenna, the two-stage amplifier eliminates the need for complex and challenging onboard filter and amplifier circuits to reduce development time. It provides a gain of more than 25 dB and has a noise figure of less than 4 dB.
The TFM.110A is available in a surface-mount package that measures 15.50 x 15.50 x 2.76 mm and requires a DC supply from 1.8 to 5.5 V. It is suitable for use in autonomous vehicles, precision agriculture, automotive, unmanned aerial vehicles (UAV) and robotics.
