F1455NKGK8

Variable Gain Amplifier from Axiro Semiconductor Inc.

Amplifier, Digital Variable, 1400 to 2300 MHz, 23 dBm, 32.8 dB, 3.9 dB NF, KLin RF Amplifier, DSA and PA driver

Status: Standard | Datasheet: Request Data Sheet | RoHS Compliance: Rohs Compliant

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