F1421

RF Amplifier 1.7GHz to 2.2GHz Description The F1421 is a high gain / high linearity RF amplifier used in highperformance RF applications. The F1421 provides 20.3dB gain with a +40dBm OIP3 and 5.5dB noise figure at 1.9GHz. This device uses a single 5V supply and 138mA of ICC. In typical base stations, RF amplifiers are used in the RX and TX traffic paths to boost signal levels. The F1421 amplifier offers very high reliability due to its construction using silicon die in a QFN package. Typical Applications  Multi-mode, multi-carrier transmitters  PCS1900 base stations  DCS1800 base stations  WiMAX and LTE base stations  UMTS/WCDMA 3G base stations  PHS/PAS base stations  Public safety infrastructure F1421 Datasheet Features  Broadband 1.7GHz to 2.2GHz  20.3dB typical gain at 1.9GHz  5.5dB noise figure at 1.9GHz  +40dBm OIP3 at 1.9GHz  +23dBm output P1dB at 1.9GHz  Single 5V supply voltage  ICC = 138mA  -40°C to +105°C operating temperature ...
