Product Brief
The BFP740 is a linear very 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 = 45 mA. With its high linearity at currents as low as 10 mA (see Fig. 5-8) the device supports energy efficient designs. The typical transition frequency is approximately 45 GHz, hence the device offers high power gain at frequencies up to 11 GHz in amplifier applications. The device is housed in an easy to use plastic package with visible leads.
