2.1 Schematic and BOM

The TRF37x73/75 EVM for RF gain blocks comes in a 2 × 2 WSON package. The device type is visually identified in component U1 by the 0402 selection resistors TRF37A73, TRF37B73, TRF37C73, TRF37A75, TRF37B75, and TRF37C75.

The TRF37x73 are a family of 3.3-V, RF gain blocks that have 3 gain variants (A73 = 12 dB, B73 = 15 dB, and C73 = 18 dB). The TRF37x75 are a family of 5-V, RF gain blocks that have 3 gain variants (A75 = 12 dB, B75 = 15 dB, and C75 = 18 dB).

The TRF37x73/75 EVM schematic is shown in Figure 2-1.
