About RF Cafe

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

FCC Unleashes Backhaul Spectrum

The FCC has voted unanimously to free up a maximum of 650 MHz of spectrum for mobile wireless backhaul and make it easier and more cost effective for wireless companies to use point-to-point microwave links to deliver their service, particularly in rural areas. Read on…

Rosy Picture for Point-To-Point

The Dell' Oro Group's 5-Year Forecast Report on the microwave transmission industry projects that the point-to-point microwave transmission market will exceed $6 billion by 2015. The report states that demand for mobile backhaul is expected to trigger an increase in radio transceiver shipments, which is expected to reach nearly 3 million units. Read on

The Invasion of Digital Devices

It should really be no surprise to anyone that defense system manufacturers are attempting to remove as much analog (read: microwave) content in the receive chain as they can between the antenna and the point at which the signal is downconverted to baseband. Testament to this fact are the comments from a large number of manufacturers quoted in the July issue of the Journal of Electronic Defense. There are enormous advantages to working with a signal in the digital domain: extraordinary amounts of signal processing can be performed in near real-time, the systems themselves can be smaller, and the tweaky nature of analog components can be dispensed with, to name a few.

While this is an enviable goal, and one that is all but a necessity considering the complexity and increasing density of threats, the fact remains that with the current state of the art in analog to digital converters, only a single stage of those analog components can actually be eliminated. That's because it's currently possible to sample only at an input frequency of about 2 GHz. Above that frequency, the traditional mixing stages, low noise amplifiers, and filters that form downconversion schemes are still required and are likely to be for a very long time. Converters, unlike microprocessors, don't follow Moore's Law and massive enhancements are years in coming. On the transmit side, the picture is even brighter for microwave manufacturers because high-power components cannot be replicated by digital techniques, and until someone figures out how to generate RF power with a digital device, RF power transmission will remain firmly in the microwave camp. The signal may be digital but the devices that transmit it will continue to be analog.

As interference to defense systems is on the increase, the need for filters is also virtually assured. More and more frequently, we receive requests
to mitigate interference issues in systems installed in the field. This can result from the fact that interference issues were not correctly addressed when a system was installed or new interference has popped up since then. For more than 20 years, we've been solving problems like these with high-performance filters that have extremely high rejection, high power handling ability, and exceptional ruggedness.
