Hirose Launches Fully Shielded Hybrid FPC-to-Board Connector Supporting 40 Gbps

Hirose has introduced the BK35 Series, a hybrid FPC-to-board connector designed for high-speed and high-frequency applications. The connector combines power and signal contacts in a fully shielded structure and supports data transmission speeds of up to 40 Gbps and RF signal transmission up to 40 GHz.

The BK35 Series is intended for compact electronic devices including smartphones, tablets, notebook PCs and wearable devices where space is limited and EMI performance is important.

Compact Hybrid Design

The BK35 Series features a 0.35 mm pitch, 2.2 mm depth and 0.6 mm stacking height. The hybrid design combines power and signal contacts in a single connector, including four power contacts rated at 2.5 A each. Hirose says the fully shielded structure blocks both radiated and incident magnetic fields to help maintain signal integrity in high-speed applications.

The connector also features a fully armored design to improve durability and help protect the housing from damage caused by mating misalignment.

High-Speed Performance

The BK35 Series supports data transmission speeds of up to 40 Gbps and RF signal transmission up to 40 GHz. According to Hirose, the connector provides the following maximum voltage standing wave ratio (VSWR) performance:

• 0-5 GHz: 1.3
• 5-10 GHz: 1.4
• 10-20 GHz: 1.5
• 20-40 GHz: 1.8

The BK35 Series is designed for compact electronic systems requiring high-speed data transmission and RF performance.
