A-13.
A shunt peaking coil for Q2.
A-14.
A decoupling capacitor for the effects of R2.
A-15.
A part of the low-frequency compensation network for Q1.
A-16.
A series peaking coil for Q1.
A-17.
A swamping resistor for L2.
A-18.
L1, L2, and R5.
A-19.
R9 and C5.
A-20.
The gain increases.
A-21.
The gain decreases.
A-22.
To provide maximum impedance at the desired frequency.
A-23.
Yes.
A-24.
By changing the value.
A-25.
Transformer coupling.
A-26.
It uses fewer components than capacitive coupling and can provide an increase in gain.
A-27.
A step-down transformer.
A-28.
A too-narrow bandpass.
A-29.
By using an optimumly-coupled transformer.
A-30.
Low gain at the center frequency.
A-31.
A swamping resistor in parallel with the tuned circuit.
A-32.
RF transformers are used and the transistor is neutralized.
A-33.
Degenerative or negative.
A-34.
By neutralization such as the use of a capacitor to provide regenerative (positive) feedback.
A-35.
C2 and the secondary of T1.
A-36.
R1 provides the proper bias to the base of Q1 from VBB .
A-37.
R2 provides the proper bias to the emitter of Q1.
A-38.
The output would decrease. (C4 decouples R2 preventing degenerative feedback from R2.)
A-39.
C5 and the primary of T2.
A-40.
Four.
