PASSIVE COMPONENTS APPLICATION NOTES AND WHITE PAPERS

  • Ferrite Beads Demystified

    High resolution, high performance converters and radio frequency (RF) systems require good power supply noise filtering and high frequency crosstalk reduction between analog and digital domains. An effective method for filtering high frequency power supply noise and cleanly sharing similar supply rails is the use of ferrite beads. A ferrite bead is a passive device that filters high frequency noise energy over a broad frequency range, where it then becomes resistive and dissipates noise energy in the form of heat. This application note presents and discusses Analog Devices’ products that demonstrate the effects of ferrite beads as output filters.

Connectorized Ceramic Diplexers and Multiplexers Connectorized Ceramic Diplexers and Multiplexers

Ceramic diplexers and multiplexers offer performance benefits that fall between Cavity and Lumped element diplexer capabilities and characteristics. Most often, they’re used because of a system’s size constraints. Ceramic diplexers are offered as non-hermetic surface mount designs or in hermetic housings with connectors.

E-Band Diplexer E-Band Diplexer

Traditional 6 to 42 GHz microwave bands are becoming crowded with rapidly growing mobile backhaul data streams. MtronPTI’s E-Band Microwave Diplexer enables gigabit-per-second data rates in backhaul, data consolidation and enterprise direct connect applications.

2-18 GHz Bandpass Filter Series 2-18 GHz Bandpass Filter Series

DLI’s 2-18 GHz bandpass filters are ideal for use in applications involving the C, X, and Ku bands, satellite communications, satellite TV, weather and radar, and military communications. They feature frequency stability over temperature, full shielding, and a compact sizes across the entire line.

Passive Splitters/Combiners Passive Splitters/Combiners

ETL offers a variety of 2, 3, 4, 8, and 16-way splitters/combiners operating in the L-band (850-2150 MHz). They’re ideal for applications involving telecom infrastructures, satellite systems, microwave links, test and instrumentation, military communications, and radar networks. Types include DC and 10 MHz pass on all ports, DC and 10 MHz block on all ports, and DC and 10 MHz pass on port 1 to Common & Blocked on the rest. For information on the individual model’s specifications and RF performance in the L-band, download the available datasheets.

Waveguide Filters Waveguide Filters

API Technologies designs and manufactures waveguide filters to 40 GHz with peak power level handling of up to 50 kW. The inherent high Q of Waveguide allows for the design of filters with the lowest possible loss.

X-Band 10W Limiters X-Band 10W Limiters

The TGL2217 and TGL2217-SM are Qorvo’s new wideband GaAs VPIN limiters designed to protect sensitive receive channel components against high power incident signals. These limiters do not require DC bias, and are able to achieve low insertion loss in a small form factor, allowing for simple system integration with minimal impact on performance.

Surface Mount Lowpass Filter Series Surface Mount Lowpass Filter Series

DLI’s series of surface mount lowpass filters are compact and fully shielded. They feature frequency stability over temperature, excellent repeatability, 50Ω characteristic impedance, and a -55oC to +125oC operating temperature.

Custom Cavity Filters: CF Series Custom Cavity Filters: CF Series

PDI’s custom cavity filter offerings cover the 400MHz to 20GHz range and are available in bandpass, cross-coupled bandpass, and bandreject configurations. They’re ideal for use in ground-based radar, radio receivers, radio transmitters, and base station systems.
