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.

Compact High-Performance Ceramic Diplexer

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.
