Description
Features
The F1420 is a high gain / high linearity RF amplifier used in high-
performance RF applications. The F1420 provides 17.4dB gain
with +42dBm OIP3 and 4.5dB noise figure at 960MHz. This device
uses a single 5V supply and 105mA of ICC.

Broadband 700MHz to 1.1GHz
17.4dB typical gain at 960MHz
4.5dB noise figure at 960MHz
+42dBm OIP3 at 960MHz
In typical base stations, RF amplifiers are used in the RX and TX
traffic paths to boost signal levels. The F1420 amplifier offers very
high reliability due to its construction using silicon die in a QFN
package.
+23.2dBm output P1dB at 960MHz
Single 5V supply voltage
ICC = 105mA
-40°C to +105°C operating temperature
Competitive Advantage
. 50Ω single-ended input / output impedances
In typical base stations, RF amplifiers are used in the RX and TX
traffic paths to boost signal levels. The F1420 amplifier offers very
high reliability due to its construction using silicon die in a QFN
