The TRF3302 is a versatile LNA that is configurable to optimize performance for a single GNSS band matching for either the upper or lower L-band frequencies, or configurable for a wide frequency coverage across multiple GNSS bands from 1165MHz to 1630MHz.

The TRF3302 features an integrated wideband output match, eliminating external matching components to interface with GNSS receivers, thus reducing BOM count and solution size. The required off-chip input match allows flexibility to optimize device performance to the system-specific requirements. A two-element match (see Figure 6-2) suffices for single GNSS band operation. A four-element match (see Figure 6-3) allows wide multiband matching to optimize performance across NF, gain, and S11.

The 6-pin WSON-FCRLF package has wettable flanks that allows visual inspection of solder joints by automatic optical inspection (AOI), thus improving product reliability without the added manufacturing cost of expensive X-ray inspection systems. The TRF3302 pinout (see Figure 4-1) is optimized for PCB layout and RF performance by having RF ground pins (VCC and GND) around the RFIN pin, and EN and GND around the RFOUT pin.
