Innovation: The Answer to a Flat Market By Harvey Kaylie, Founder and CEO, Mini-Circuits
Some might say business seems flat lately. The financial crisis in Greece has led to economic turmoil in the EU. Opportunities in China have slowed, and when China sneezes, the whole world feels it. Read More...

Will OpenRFM Shake Up the Microwave Industry? By Barry Manz
Throughout the history of the RF and microwave industry there has never been a form factor standardizing the electromechanical, software, control plane, and thermal interfaces used by integrated microwave assemblies (IMAs) employed in defense systems. Rather, every system has been built to meet the requirements of a specific system, which may be but probably isn’t compatible with any other system. It’s simply the way the industry has always responded to requests from subcontractors that in turn must meet the physical, electrical, and RF requirements of prime contractors. Read More...

Band Reject Filter Series Higher frequency band reject (notch) filters are designed to operate over the frequency range of .01 to 28 GHz. These filters are characterized by having the reverse properties of band pass filters and are offered in multiple topologies. Available in compact sizes. RLC Electronics
SP6T RF Switch JSW6-33DR+ is a medium power reflective SP6T RF switch, with reflective short on output ports in the off condition. Made using Silicon-on-Insulator process, it has very high IP3, a built-in CMOS driver and negative voltage generator. Mini-Circuits
Group Delay Equalized Bandpass Filter Part number 2903 is a group delayed equalized elliptic type bandpass filter that has a typical 1 dB bandwidth of 94 MHz and a typical 60 dB bandwidth of 171 MHz. Insertion loss is <2 dB and group delay variation from 110 to 170 MHz is <3nsec. KR Electronics
Absorptive Low Pass Filter Model AF9350 is a UHF, low pass filter that covers the 10 to 500 MHz band and has an average power rating of 400W CW. It incurs a rejection of 45 dB minimum at the 750 to 3000 MHz band, and power rating of 25W CW from 501 to 5000 MHz. Werlatone
LTE Band 14 Ceramic Duplexer This high performance LTE ceramic duplexer was designed and built for use in public safety communication and commercial cellular applications. It operates in Band 14 and offers low insertion loss and high isolation to enable clear communications in the LTE network. Networks International
The Series 620 snap-in product line includes color-coded plugs and receptacles. The color-coded connectors help prevent accidental mismating when several connectors are installed on the same equipment. With an OD of only 11.5mm, the series offers a smaller option. Binder-USA Go

•The Design of Ultra Narrowband Amplifiers Using Small-Signal Varactor Upconverters This paper presents a method of realizing tunable microwave amplifiers with ultra narrow bandwidths that can be less than 0.5% by the use of a varactor up-converter (UC). Planar Monolithics
•Directivity and VSWR Measurements Return loss and VSWR measurements are complicated by the finite performance of the directional device used to measure the reflected power. The only accurate and convenient way to make return loss measurements is with a well matched high directivity directional coupler or bridge. Marki Microwave
