Product Information
Application Circuit
Notes:
1. DNP = Do not place this component.
2. Distance “D1” measured from U1, pin 4 to edge of Cx (where x = 2, 3, or 4).
a. D1 = 0.620” to C2 (for use with AH103-PCB1750)
The 2.0 pF input tuning capacitor is placed .045” to the left of “C2” shown on the silk
screen. The shunt capacitor is placed directly on the right and adjacent to the input
blocking capacitor C1.
b. D1 = 0.450” to C3 (for use with AH103-PCB1900)
c. D1 = 0.310” to C4 (for use with AH103-PCB2140)
3. A voltage regulator is used in this circuit (U2) to drop the +9 V to a +5 V usable supply for the first
internal amplifier. It is permissible to remove the regulator and operate the 1st amplifier stage
directly off of +5 V supply onto Test Point 1 (TP1). The use of a +5 V supply on the 1st amplifier
stage requires a dropping resistor of 6.8 .
4. A +4.5 V supply can also be used to bypass the 6.8 and can be applied to Test Point 2 (TP2).
