List of components:
C1 = C2 = C7 = C8 = 2 to 9 pF film dielectric trimmer (cat. no. 2222 809 09002)
C3 = C6 = 3,9 pF ceramic capacitor (500 V)
C4 = 100 pF feed-through capacitor
C5 = 100 nF polyester film capacitor
L1 = stripline (24,0 mm × 6,7 mm)
L2 = 10 turns closely wound enamelled Cu-wire (0,4 mm); int. diam. 4 mm
L3 = 2 turns enamelled Cu-wire (0,6 mm); Ferroxcube tube core, grade 3B5 (cat. no. 4313 020 15170)
L4 = 12,6 nH; 2,5 turns enamelled Cu-wire (0,7 mm); int. diam. 4 mm; length 3 mm; leads 2 × 5 mm
L5 = Ferroxcube wideband h.f. choke, grade 3B (cat. no. 4312 020 36642)
L6 = stripline (28,4 mm × 6,7 mm)
R1 = R2 = 10 Ω carbon resistor
L1 and L6 are striplines on a double Cu-clad printed circuit board with P.T.F.E. fibre-glass dielectric (εr = 2,74);
thickness 1⁄16 inch.
Component lay-out and printed-circuit board for 470 MHz test circuit are shown in Figs 7 and 8.
