Richardson RFPD Engineers Overcome Automotive SDARS Design Challenges
Company
Richardson RFPD, an Arrow Company, is a specialized electronic component distributor providing design engineers with deep technical expertise and localized global design support for the latest new products from the world’s leading suppliers of RF, wireless, internet of things (IoT) and power technologies. The company’s specialized knowledge in RF, wireless, IoT and power management engineering helps customers accelerate time to market, find complete solutions, save development costs, and, ultimately, improve design performance.
Challenge
The need to add new antenna elements a vehicle rooftop antenna module to keep up with customer demand for in-vehicle information/entertainment is increasing. Crosstalk (coupling) between those antenna elements within the module is one of the most critical and challenging issues that antenna engineers are faced with and struggle to overcome. This crosstalk between the antenna elements results in leakage of unwanted signals, which are picked up by an antenna. A specific example is the influence of the cellular antenna element, which causes interference, overloading, and added noise in the low-noise amplifiers (LNAs) of the rest of the antenna elements.
Richardson RFPD designers were tasked with developing a robust LNA lineup for a satellite digital audio radio service (SDARS) antenna that has higher immunity to external interfering signals. The LNA lineup was for the SDARS antenna designed for multiband antennas for rooftop automotive applications to fit in a very small volume to satisfy automotive market requirements.
Solution
The designers used AWR software, specifically Microwave Office circuit design software, inclusive of the network synthesis wizard and iFilter™ integrated filter synthesis wizard, to simulate the complete LNA circuit.

It would have been impossible to invent the Microlithic mixer without adopting AWR’s Microwave Office simulation technology. By using a modern CAD approach, we successfully condensed four decades of hard-earned mixer design knowledge into 12 months of intense simulation and hardware development. Designing in software has saved us incalculable amounts of time and money.
