1. INTRODUCTION

The US Air Force, National Radar Cross-Section Test Facility (NRTF) at White Sands NM is pursuing a modular design for a wideband, high power, pulsed Ka band amplifier to augment the current Tier III RAMS facility. The Contractor shall meet the minimum requirements stated in this Requirements Document and Appendix 1.0

The design shall be based on integrating and phase cohering 8 (100 W) modules to achieve the desired output. The NRTF will initially procure between 6-10 (100 W) modules which translates to an integrated amplifier of 8 modules with 2 spares.

2. DELIVERY

Delivery of all modules shall occur no later than 10 Dec 21.

3. PROJECT SCHEDULE

The Contractor shall provide a complete milestone schedule that denotes major activities, demonstrations and acceptance testing.

4. TECHNCAL INTERCHANGE AND ACCEPTANCE

The contractor shall conduct the following reviews:

Kick-off/ Technical Interchange Meeting (TIM)

Mid-Term Program Management and Progress Meeting

Acceptance Test (PCA/FCA)

Assembly Drawings

Theory and Operation Manual

These meeting shall be conducted in a format of the Contractor’s choosing and shall cover the overall technical approach, constraints, methods and techniques being examined, performance metrics and results.

5. REQUIRED DOCUMENTS

The Contractor shall provide performance to plan status reports and schedule updates to the AF

Project Manager per the frequency in Table 5-1. All documents are subject to Government acceptance and approval.
