Product Brief

The BFP450 is a high linearity wideband NPN bipolar RF transistor. The collector design supports voltages up to VCEO = 4.5 V and currents up to IC = 170 mA. With its high linearity at currents as low as 50 mA the device supports energy efficient designs. The typical transition frequency is approximately 24 GHz, hence the device offers high power gain at frequencies up to 3 GHz in amplifier applications. The device is housed in an easy to use plastic package with visible leads.
