TFM.120A

TFM.120A is a surface mount GNSS front-end module covering L1+B1+G1/L2/L5+L-band for multiband high-precision applications that require the full spectrum of GNSS constellations. The TFM.120A is a dual input single output and 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 a low noise figure. The TFM.120A captures the required additional RF circuits in modular form, allowing the designer to simply place the TFM.120A between their GNSS antenna and GNSS receiver. The TFM.120 offers <gt/> 25dB gain across all applicable bands while maintaining a high Input P1dB of -25dBm or better.
