7.1 Application Information

The TRF3302-Q1 is a single-ended input and output LNA. The device is typically used in GNSS global positioning systems to improve the sensitivity of the GNSS receivers. This improvement comes by virtue of the 0.8dB NF of the device combined with ≈17dB of gain for upper or lower L-band GNSS systems. In systems where the receive antenna is far from the GNSS receiver and connected by a cable or a long trace, the TRF3302-Q1 helps improve the signal immunity to noise pickup by amplifying the signal before the signal reaches the GNSS receiver while adding minimal amplifier noise. For systems that need to simultaneously support upper and lower L-bands, a broadband input matching network is used with the TRF3302-Q1 (see Section 7.2.1).
