Business Insider estimates 94 million connected cars to ship in 2021, which represents approximately 82% of all cars shipped that year alone. There are currently two types of ways cars are connected. Embedded cars utilize a built-in radio and antenna connecting to local cellular networks. Tethered cars use a wireless connected device, typically a cell phone to provide the data connectivity. These vehicles achieve this via Bluetooth or a USB cable.
In addition to data connectivity, cars have GPS for navigation and emergency services, satellite radio (Sirius), hands-free calling, sensor and data gathering (tire-pressure monitors), and key-less entry/start. Some of these systems (tire-pressure monitoring) can utilize an embedded or board level antenna; however, other critical (emergency services) or data intensive systems (navigation, satellite radio) require an external application specific antenna. I-PEX Connectors offers a robust and diverse product offering to suit RF interconnectivity needs within all of these systems utilizing I-PEX's patented iFit MHF Series.
The MHF family of connectors provides automotive OEM module manufacturers a right-sized solution for their RF needs. While the frequency ranges from DC to 15GHz (MHF5L), the majority of the frequencies used in automotive, DC to 6 GHz, can be realized with the MHF I family. In addition to a mated board height maximum of 2.5 mm (1.8mm OD wire) to 3mm (2.0mm OD wire), the MHF I Micro RF Coaxial Connector offers the most versatility in choosing the right cable for your application. Please consult with your I-PEX Connector representative to confirm compatibility.
Repeatability and consistency are critical to ensuring device operation. The MHF Series consistently has a 1.3 VSWR max from DC-3 GHz and a 1.5 VSWR max from 3GHz-6GHz. To assist with durability, I-PEX offers a 4-pad layout in addition to the 3-pad configuration.
I-PEX Connectors understands that automotive applications present unique problems that stationary RF systems do not encounter, particularly shock and vibration. Cars are in motion, roads are uneven, and this generates mechanical harmonics that could cause connectors to disengage over time. Coming soon in 2017 is the MHF LK system. This innovative solution will be available in cable sizes (1.13 mm OD & 1.37 mm OD) to suit various insertion loss and cable length needs. Additionally, the initial mating disengagement force of 28.3 N outperforms the standard MHF I Series of 17.2 N. Even at 30 cycles, the MHF LK, at 15.1 N, performs better than the MHF 1, at 6.4 N.
