This is a RF amplifier circuit for 10Mhz - 500Mhz input signal. The RF amplifier is using single power transistor BFR540 as the main component to amplify the input signal. The BFR540 is an NPN silicon planar epitaxial transistor in a SOT23 plastic package. BFR540 featured with high power gain, low noise figure, high transition frequency and have gold metallization ensures excellent reliability.
