F1455

TX RF VGA with KLIN™ Feature

The F1455 is a High-Gain / High-Linearity 1400 MHz to 2300 MHz TX Variable Gain Amplifier used in transmitter applications. The F1455 TX VGA provides 32 dB maximum gain with +39 dBm OIP3 and 4 dB noise figure. Up to 29.5 dB gain control is achieved using the combination of a digital step attenuator (DSA) plus KLINRF variable gain amplifier gain adjustment. This device uses a single 5 V supply and 216 mA of ICC. This device is packaged in a 6 mm x 6 mm, 28-pin QFN with 50 Ω single-ended RF input and RF output impedances for ease of integration into the signal path.
