Low k dielectrics with low dielectric absorption (DA), such as multilayer organic capacitors, can benefit sample and hold circuits, where DA can cause voltage error at the output due to charge recovery.
Printed-circuit-board (PCB) materials with high dielectric constants can help miniaturize microwave circuits, but engineers using these materials must be aware of the impact of loss and dispersion on their designs.
By keeping in mind LTCC’s limitations as well as applicable design rules, engineers can benefit from its use—particularly in compact RF and microwave components.
A high-speed material has been formulated to enable the design of low-skew differential circuits at speeds to 100 Gb/s.
Careful choice of shielding materials can eliminate interference problems in a cost-effective manner.
Understanding dielectric material parameters can help simplify the process of choosing the right printed-circuit-board (PCB) material for a design.
