High Gain and High Linearity Low Noise Amplifier BFP760 for 2.4 GHz WLAN

Description
The BFP760 is a linear low noise wideband NPN bipolar RF transistor. The device is based
on Infineon’s reliable high volume silicon germanium carbon (SiGe:C) heterojunction bipolar
technology. The collector design supports voltages up to Vceo=4.0 V and currents up to Ic=70 mA.
With its high linearity at currents as low as 10 mA the device supports energy efficient designs.
The typical transit frequency is approximately 45 GHz. The device is housed in an easy to use plastic
SOT-343 package with visible leads.
