IPDiA's Broadband Silicon Capacitor (BBSC) Product Line at 40 GHz

IPDiA's Broadband Silicon Capacitor (BBSC) Product Line at 40 GHz

The BBSC capacitor series from IPDiA provide superior broadband performance, stability and reliability for all broadband optoelectronics and high speed data systems. They provide broadband performances better than 0.4 dB of insertion loss up to 40 GHz, as well as very high stability of the capacitance over temperature (50 ppm/°C), voltage variation, and are highly reliable.

The BBSC capacitors have an extended operating temperature ranging from -55 to 150°C. The unique technology of integrated passive device in silicon, developed by IPDiA, offers unique performances with low insertion loss, low reflection and excellent phase stability from 16 kHz to 40 GHz:

• Ultra-low insertion loss < 0.4 dB up to 40 GHz;
• Flat frequency response;
• Excellent return loss > 16 dB;
• Resonance free and no phase discontinuity;
• Lower dielectric absorption (0.05%) compared with NP0/X7R;
• No AC distortion thanks to zero piezo effect;
• Excellent reliability exceeding X7R ceramics by a factor 10 (FIT);
• Reliable and repeatable performances obtained thanks to a fully controlled production line with high temperature curing (above 900°C) generating a highly pure oxide.

These broadband capacitors with ultra-deep trenches in silicon have been developed using a semiconductor process which enables the integration of trench MOS capacitors providing high capacitance value - for example, 100 nF in a 100 µm low profile 0402 SMT (P/N: 939.114.424.510) or 10 nF in a 100 µm low profile 0201 SMT (P/N: 939.114.423.410). Thanks to the adequate land pattern of the pads underneath the component, the impedance discontinuity of the transmission line can be mitigated. The BBSC series are compliant with standard JEDEC assembly rules, making the product fully compatible with high speed automated pick-and-place manufacturing operations. These capacitors are RoHS compliant and are available with either ENIG terminations or lead-free pre-bumped depending on the case size. The BBSC capacitors are suitable for DC blocking, coupling and bypass grounding applications in all optoelectronics/high-speed data, transimpedance amplifiers (TIA), receive-and-transmit optical sub-assembly (ROSA/TOSA), synchronous optical networking (SONET), as well as broadband test equipment and broadband microwave/millimeter-wave.
