RF IN
R5 is used to maintain the correct bias level at higher supply voltages and is also required in this configuration. The RC network of R2
and C3 should be kept physically as short as possible. R2 can be adjusted as required to improve the impedance matching. R6 and
R7 reduce the typical gain by increasing the emitter resistance. L1 should be at least 200 Ω reactive at the lowest operating
frequency. C1 and C2 should be less than 10 Ω at the lowest operating frequency. C4 and C5 improve gain flatness.
