Radio Frequency Design
Any products and systems that utilise radio in any manner need RF design input. sensRAI’s RF team has extensive experience that extends from HF to 60GHz and includes areas such as Antenna design, RF filter and multiplexer design, RF amplifier design, Frequency synthesisers and oscillators and frequency translating upconverters, down-converters and mixers.
Generally the RF design process is as follows:
- Capturing the client's RF performance requirements
- Understanding the product's physical constraints and operating environment
- Capturing the DC power constraints
- Modelling the RF environment and link budgets
- Deciding the mix of active and passive components given the DC power and product physical constraints
- Designing and Modelling the full RF circuits using tools such as
- Doing the RF PCB Design with initial RF BOM
- Prototyping the RF stages and bench testing them together with the prototype main PCB to identify any co-interference problems
- EMC testing the RF stages and designing any suppression housings as required or utilising off-the-shelf cans
- Field testing the prototype RF stages
- Integrating the RF PCB with the main PCB in conjunction with the electronic engineering team
- Bench testing the combined prototype
- Field testing the combined prototype
- Finalising the RF section of the main BOM
The team has experience in design and development of passive RF devices such as filters and multiplexers in the frequency range from 10MHz to 70GHz and using technology solutions such as Combline and Interdigital, Microstrip and Stripline as well as suspended-substrate-stripline.
