Kaltman Creations RF-ResQ Wireless Solution

Kaltman Creations LLC in Atlanta, makers of the Invisible Waves brand tools for handling wireless interference, announces its RF-ResQ (Receiver Enhancement System), an antenna signal processor that promises to rescue and salvage unusable RF spectrum, substantially reduce interference and more. The company offers RF-ResQ as its solution to RF congestion and “spectrum squeeze”.

Installed between the antennas and receivers, the RF-ResQ works with industry-standard antennas, in analog and digital wireless mic systems in the 470- to 928MHz range. Frequency, gain and routing assignments are easily performed via a LAN or USB/laptop connection to the rack unit. With its router capability, the RF-ResQ can be used either as a direct replacement or in conjunction with existing antenna distribution system.

Housed in a rugged single-rackspace unit, the RF-ResQ is said to be the world’s first stand-alone wireless microphone filtering system employing multiple military-spec, high-Q bandpass filters. ResQ will clean up the received RF spectrum, allow for closer adjacent channel spacing (potentially doubling available channel counts without sacrificing power), remove the issue of intermodulation effects, and improve the reception of weaker transmissions.

RF-ResQ’s onboard 8-channel antenna distribution amplifier with RF router allows its filters to adapt to various receiver and distribution configurations. This provides one filter/frequency per receiver channel, meaning that the user’s receiver only sees its assigned transmitter frequency and nothing else, with no out-of-band RF interference to bog down or de-sensitize the receiver’s input. Alternatively, users can select “combined signal routing” to feed integrated receiver/distribution systems, as found in some newer digital mic systems.

RF-ResQ assigns a single, frequency-cleaned-up, bandpass filtered feed for each transmitter’s frequency, and its eight amplifiers can maximize the individual RF signals up to 10 dB, so there is no need for an amplified antenna.

DiverseQ, the RF-ResQ’s new antenna diversity technology, pre-filters the antenna A/B signals in the IF stage for fast, accurate and quiet antenna switching. This improved, “best signal detection” function is performed within the RF-ResQ, so there is no need for a 2-antenna connection at the receiver input.
