Substrate height, dielectric constant, loss tangent, interconnect metal thickness, component tolerance, pad width, pad length and pad gap are model input parameters. Models account for up to two higher-order resonant frequency pairs beyond the fundamental series resonant frequency. Accurate effective series resistance (ESR) is modeled over the frequency range. A Sim mode switch allows pad stack effects to be disabled.
The applications for which these parts are intended require small, surface-mountable (SMT) devices with low insertion losses and reflections across RF frequencies extending from the tens of kHz to the tens of GHz, and temperatures typically ranging from -55 to +125 °C.
Applications are primarily found in the “signal integrity” market including optoelectronics/high-speed data; ROSA/TOSA (Transmit/Receive optical subassemblies); SONET (Synchronous Optical Networks); broadband test equipment; and broadband microwave and millimeter wave amplifiers and oscillators. The BB series provide surface-mountable, 10 nF or 100 nF capacitors that provide resonance-free, low insertion loss, low reflection operation over extremely large RF bandwidths.
