Uncertain Times for DefenseIn Defense of DARPA; Lamenting Bell Labs
By Barry Manz

A federal agency like DARPA is a sitting duck for politicians and assorted other critics. It has come up with some truly bizarre programs over years that ultimately either delivered no tangible results, were canceled before they could cause any damage, or attempted to answer questions that nobody was asking or needed answers to.

The Elephant in the Room
By Barry Manz

Let’s hear it for the federal government. With its now standard blaming, waffling, cowering, and blind obedience to ideology, the Obama administration and Congress let $85 billion in immediate cuts and hundreds of billions more over a decade take effect. A conclusion to this sorry era in our nation’s history is far from over, as the real work now begins: wrangling over the new federal budget, the true long-term effects of sequestration will be, and a lot more. However one thing is certain: The defense industry, including those like the microwave industry that rely on it, will take a beating.

Nobody doubts there is more fat in Pentagon budgets than cheap bacon, and they cannot be leaned out to the degree now required by law without goring the country’s security, reducing its technology base, or further delaying vital programs. Unfortunately, DoD hasn’t done itself any favors in its handling of the F-35 Joint Strike Fighter program, the ever-hungry elephant in the room. DoD is staking the future of U.S. fighter aircraft on the F-35, as it is the only stealth fighter in production and will replace thousands of A-10, F-15, F-16, and F-18 fighters for the Air Force, Navy, and Marines Corps.

As the F-35 embodies massive technical feats it shouldn’t be surprising that making all of these first-of-their-kind systems work has cost more and taken longer than expected. Nevertheless, decision to build aircraft before being “fully cooked” was ill-conceived and will cost far more in retrofits than if the problems were solved during development. That would have delayed the program, adding to the growing tsunami of criticism. Creating three variants of the aircraft, one of which like the Harrier is devilishly complex, was also an “all or nothing” crap shoot. And on and on.

The F-35 program will continue, it will incur additional expense, more delays will be announced, and perhaps fewer aircraft will be built. The RF and microwave industry needs the F-35 and the cash that its EW, radar, communications, and avionics systems will bring. But it also needs the many other programs that are being jeopardized by this massive program.

WHITE PAPERS

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.
