Overcoming Gain Slope Issues In Microwave Modules By Dielectric Laboratories, Inc.
If you are a microwave hardware engineer, you most likely have had a few sobering experiences when testing your new design the first time. This is particularly true for wideband high frequency modules — they almost never look like the model. Many of the bigger issues come down to physics. Broadband modules (2 to 18 GHz) virtually always have gain roll-off at the high end of the band.
Spotlight On Filters
Low-Loss, Digitally Tuned Bandpass Filters MtronPTI expands their RF and microwave filter line with the introduction of digitally tuned bandpass filters. Software-defined radios and cognitive radios require flexible RF front ends, similar to frequency hopping front ends of military communication radios.
Ceramic/LC GPS Filter The 8LBCRLC-150/1575/20-O is a hybrid ceramic/LC GPS filter with a DC bypass and lightning protection. It has a center frequency of 1575+2 MHz, <1 dB insertion loss, <200 mA current, <4.5 dB insertion loss, <1.5:1 in/out VSWR, 3-dB bandwidth at 25 to 30 MHz, and more.
Fast EM-Based Filter Design Port Tuning is a methodology which allows us to tune EM layouts with circuit theory models. This power point presentation provides information on Sonnet's method of simulation.
LC Filters For Frequency Control Highest-quality, custom-designed, or standard LC filters for radio and NAV/COM are now available, including bandpass, low pass, high pass, and notch LC filters. With rapid prototyping, PDI offers a quick turnaround for any frequency from 5 MHz to 100 MHz. Made in the U.S.A.
Multiplexer For Radar, EW, And ELINT The NF29525 is a multiplexer with an integrated low-noise amplifier. It covers the 2- to 18-GHz frequency range and has been specifically designed for agile receiver front ends and directional finding systems.
1000- To 15000-MHz Cavity Notch Filter The cavity notch filter has a center frequency of 1000- to 15000-MHz, maximum input power 100 watts, operating temperature range -40 degrees C to +85 degrees C, and can withstand 25 G's of shock and 10 G's vibration.
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.
The ClearPlex Waveguide Ceramic Filter has been designed to replace high-end air cavity filters in macro-cell wireless applications. This datasheet includes a detailed description of the filter, as well as information on its features.
This traveling wave tube amplifier (TWTA) covers the 2- to 4-GHz frequency range and is suitable for applications involving test and measurement, electronic warfare (EW) simulation, RFI/EMI/EMC testing, electronic countermeasures (ECM), and antenna pattern and radar-cross section measurements.
This brochure contains information on COM DEV's offerings as they relate to surface acoustic wave (SAW) filters. General information on SAW bandpass filters is included, as well as information on bandpass filter types, performance capabilities of SAW bandpass filters, and more.
The HEVC-1000 SDK is a software development kit that provides functionality for H.265/HEVC video encoding and decoding. It provides approximately twice the compression performance as H.264/AVC with the same video image quality, which reduces bandwidth and file size by 50 percent.
