Technical Manual

13-12
Notes:
1. For optimum performance, order replacement diodes, transistors, and circuit
modules by Motorola part number only.
2. When ordering crystals, specify carrier frequency, crystal frequency, crystal
type number, and Motorola part number.
3. Part value notations:
p=10
-12
n=10
-9
µ=10
-6
m=10
-3
k=10

M=10

4. ITEM refers to the component reference designator. SIDE refers to the location
of the component on the board; S1=Side 1, S2=Side 2.
5. The NLD8898 RF Board Kits use a 6-layer printed circuit board.
