High Impedance Laminates

Rogers Corp.’s MAGTREX 555 high impedance laminates enable antenna designers to miniaturize VHF and UHF antennas while maintaining the bandwidth achieved in a larger design. These laminates feature a closely matched X/Y axis permeability and permittivity of six and six and a half respectively, along with low magnetic and dielectric loss below 500 MHz. MAGTREX 555 laminates are based on a ceramic / PTFE composite system, manufactured in a process similar to Rogers Corporation’s popular RT/duroid® laminates.

MLCCs

Medical and military applications where a high capacitance value is required should consider the Novacap branded MLCCs from Knowles Precision Devices (KPD). Comparable circuit designs can be achieved at typically a third to a fifth of the capacitance values because of the low ESR characteristics these parts exhibit. These RoHS Compliant, High Capacitance value BME MLC chip capacitors, are manufactured in stable Class II dielectrics X7R and X5R. The range is offered with a spread of capacitance values starting at 6.8nF and topping out at 100μF.

App Note

A new application note and business impact case study detail how Quasonix used a novel design flow combining NI AWR software and highly accurate Modelithics models to achieve first-pass success. The flow resulted in a 150-percent improvement in productivity for the design of a power amplifier (PA) used in the company’s advanced telemetry systems. Developers of telemetry products must ensure excellent agreement between simulations and performance to be confident about their efforts to optimize these designs prior to manufacturing.
