dB
where ZD = decoupling impedance in ohms. For exam-
ple, if ZD = 1 kQ, Loss = 0.214 dB.
The RF choke is not mandatory,
but including
it
improves gain by raising the dc supply voltage decou-
pling impedance. 4 turns of #26 AWG enameled wire
wound on a ferrite bead is suggested for the choke.
Low Frequency Response
The value of the blocking capacitors determines the
low frequency response of the amplifier. The following
expression is used to determine the blocking capacitor
value to yield a desired 3 dB Iowfrequency corner (fLFC).

The nearest standard value of 270 ohms would suffice.
Etiernal Decoupling Impedance
In all cases the external bias (decoupling elements)
must present an impedance which is large compared to
