Attenuators on VNA Cables when Testing Passive Devices By Ernest Werbel, Chief Engineer, Werbel Microwave LLC
Some difficulty in acquiring reliable measurements triggered a point of interest from previous experiences. Why did some technicians place precision attenuators on one or both VNA cables as part of a setup for measuring passive devices? “It’s always been there.” But like all things, there must be a reason.

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

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...
