The F1451 is a High-Gain/High-Linearity 450MHz to 1100MHz TX Variable Gain Amplifier used in transmitter applications. The F1451 TX VGA provides 32dB maximum gain with +41dBm OIP3 and 3.6dB noise figure. Up to 29.5dB gain control is achieved using the combination of a digital step attenuator (DSA) plus KLIN™ RF variable gain amplifier gain adjustment. This device uses a single 5V supply and 185mA of ICC. This device is packaged in a 6 × 6 mm, 28-QFN with 50Ω single-ended RF input and RF output impedances for ease of integration into the signal path.
