Printed Circuit Boards for the Radar Operations Center in Norman, OK

Form / Attachment / Pricing Sheet

This document contains the schematic diagrams for a "Dither Oscillator" and a "Dither Tee Circuit." It appears to be a technical drawing or design specification related to electronic components.

• Dither Oscillator Schematic: Details the power supply, oscillator circuit, and associated components (regulators, capacitors, inductors, integrated circuits like 74AC74, 74HC163, 74HC1G14GW). It specifies voltage levels (+18V, +15V, +6V, +3.3V) and includes LEDs for status indication.
• Dither Tee Circuit Schematic: Outlines a circuit with impedance matching (Z = 50 Ω) using components like resistors, inductors, capacitors, and connectors (J2, J3, J5, J6). It is labeled as Sheet 2 of 2.
• Metadata: Includes author names (Rick Rhoton, Sage Hayes, Keith Miller), title ("Dither Oscillator"), revision (1.2), and creation dates (2026-04-13 for Oscillator, 2024-02-27 for Dither Tee).

This document provides detailed technical specifications for electronic components. Bidders involved in opportunities requiring custom electronic design, manufacturing, or integration may need to review these schematics to understand specific hardware requirements, compatibility, or to propose solutions that incorporate or interface with these circuits.

Form / Attachment / Pricing Sheet

This document is an Excel spreadsheet detailing the Bill of Materials (BOM) for a "Dither Circuit PCB." It lists the individual electronic components required for the circuit, their quantities per board, part numbers, descriptions, and cost information from potential vendors (Digi-Key and Mouser).

• Item: Sequential numbering of components.
• Quantity /PCB: The number of units of a specific component needed for one printed circuit board.
• REF.: Reference designators for the component on the PCB schematic (e.g., C3, R1, U2).
• Description: A brief technical description of the component.
• Part#: The manufacturer's or distributor's part number.
• Part Cost: The cost of a single unit of the component.
• Total Cost: The total cost for the quantity of the component needed per PCB.
• Vendor 1 Cost / Vendor name: Cost and name of the first vendor (Digi-Key).
• Vendor 2 cost / vendor name: Cost and name of the second vendor (Mouser).
• Approximate per board component cost: The total estimated cost of all components for one PCB.

This BOM provides potential bidders with a detailed breakdown of the electronic components required for the dither circuit. It can be used to:

• Estimate the cost of materials for manufacturing.
• Identify potential supply chain challenges or lead times for specific parts.
• Compare pricing from different vendors.
• Understand the complexity and specific components involved in the dither circuit's construction.
