The F1478 is a high gain, two-stage RF Amplifier designed to operate within the 1800MHz to 5000MHz frequency range. Using a single 5V power supply and with low ICC, the F1478 provides 29.6dB of Gain (which can be optimized vs. bandwidth) and 1.8dB of Noise Figure. The F1478 realizes up to +37.3dBm OIP3 and 25.5dBm OP1dB at 3550MHz.  The F1478 is packaged in a 3 × 3 mm, 16-VFQFPN, with matched 50Ω input and output impedances for ease of integration into the signal path. The silicon integration approach means that external BOM components are minimized for customer applications.
