Kaltman Creations Offers RF-ResQ

Wireless solution addresses “spectrum squeeze” May 13, 2015

ATLANTA— Kaltman Creations LLC has introduced RF-ResQ, a solution intended to address “spectrum squeeze” and RF congestion.

The company describes RF-ResQ as a “receiver enhancement system” —“an antenna signal processor that can rescue and salvage unusable RF spectrum.”

“We secured the rights and ownership to advanced filtering technology that was previously used in military, nuclear plant and critical data communications and adapted it for the UHF bands used in pro audio wireless” said Kaltman Creations President Mark L. Kaltman,

Housed in a rugged single-rack space unit, the RF-ResQ is a standalone 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, remove the issue of intermodulation effects and improve the reception of weaker transmissions, the company says. 

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. Alternatively, users can select “combined signal routing” to feed integrated receiver/distribution 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. This means that there's 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. This improved function is performed within the RF-ResQ, so there's no need for a two-antenna connection at the receiver input.

Installed between the antennas and receivers, the RF-ResQ works with industry-standard antennas, in analog and digital wireless mic systems in the 470 MHz to 928 MHz range; one model – worldwide. 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.
