Objectives
The main objective was to develop two SAW filters at S-band, using lossy filter design techniques, as SAW technology offers high Q-factors and compact size.
The produced filters show excellent performance (insertion loss, passband ripple and selectivity). The size of the filter assembled in package is about 150mm2 (15x10mm2) and has a weight of 0.9 gram.
Challenges
The main challenge was to find a way to design lossy filter elements in the SAW structure in a way that was possible to implement. The task required development of advance mathematical modelling and simulation tools.
Plan
The study logic followed the tasks from statement of work. Each task was concluded by a dedicated review.
Task 1: Literature Review and Trade-offs
- Technology Review
Task 2: Preliminary Design and Technology Validation
- Preliminary Design Review
Task 3: Breadboard Design
- Design Review
Task 4 Breadboard Manufacturing
- Test Readiness Review
Task 5 Breadboard Testing
- Test Review Board
Task 6 Final Evaluation and Development Plan
- Final Review
Current Status
The program is completed with successful Test Review Board and Final Review.
