3D Printing And Its Implications For Military And Defense By Atin Angrish, Frost & Sullivan
3D printing will soon enable on-demand fabrication of weapons, electronics, and other critical military parts — but will the technology be a double-edged sword? This article presents an analysis of the current additive manufacturing technologies for military and defense forces, covering both electronics and mechanical product development.
Spotlight On Filters
Waveguide Filters, Duplexers, And Multiplexers BoCen Microwave designs and produces a complete line of waveguide filters, duplexers, and multiplexers that cover the 2- to 50-GHz frequency range. They’re ideal for radio and defense communications applications and are available in W/G flange or connectorized configurations.
Ceramic/LC GPS Filter The 8LBCRLC-150/1575/20-O is a hybrid ceramic/LC GPS filter with a DC bypass and lightning protection. Like all of ComNav’s ceramic filters, this model is suitable for applications involving remote metering, cellular systems, military C3, automatic toll systems, Wi-Fi, RF tagging, and GPS/Glonst.
Waveguide Ceramic Filter The ClearPlex waveguide ceramic filter has been designed to replace high-end air-cavity filters in macro-cell wireless applications. This line maintains a high level of performance despite its size and is less expensive than a typical air-cavity filter.
Switched Filter Banks API Technologies Switched Filter Bank designs draw from a multi-disciplined staff with many years of experience in both microwave filters and control components. API can provide integrated switched filter assemblies that not only reduce the overall mechanical footprint, but also offer improved electrical performance.
124.8-MHz Crystal Filter The FTR80220 is Precision Devices latest 124.8-MHz fundamental crystal filter. Ideal for a broad range of RF applications, this crystal filter operates on the fundamental mode, with insertion loss improved to 3 dB maximum, spurious response now 70 dB minimum, and increased bandwidths of up to 200 kHz.
Multiplexers are passive devices used to split or combine signals, usually of different frequencies. Once several frequencies are combined, a single transmission medium is used to send or receive the signals. When the application is for splitting a signal, the input is the signal source and the outputs are split into several other ports. Corry Micronics provides off-the-shelf units designed for industry specific frequency bands or custom designs based on a company's requirements. Learn more.
Software-defined radios and cognitive radios require flexible RF front ends, similar to frequency hopping front ends of military communication radios. MtronPTI’s low-loss TF010x digitally tuned bandpass filters are designed for exactly that.
The SignalHawk Series of spectrum analyzers and VNAs is the most user-friendly and accurate handheld test solution available for installing, maintaining, and troubleshooting all segments of RF communication systems.
RLC Electronics surface-mount band pass filters offer excellent frequency response characteristics with low insertion loss. RLC offers various package options and configurations to meet customer requirement up to 6 GHz.
Mike Howard, VP of filter engineering for MtronPTI, discusses his company’s initiatives in expanding their filter product portfolio to support their customer’s need for agile selectivity closer to the antenna.
