The need to add new antenna elements in a vehicle rooftop antenna module to keep up with customer demand for in-vehicle information and entertainment is increasing. Crosstalk between those antenna elements within the module is one of the most critical and challenging issues that antenna engineers struggle to overcome. 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.
In this reference design, Richardson RFPD designers developed 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 an SDARS multiband antenna designed for rooftop automotive applications to fit in a very small volume, satisfying automotive market requirements, and included GRF2073 and GRF4002 amplifiers from Guerrilla RF as well as B39232B3416U41C and B39232B3447U41C filters from Qualcomm.
