High-Q antenna signal processor opens unusable
portions of the RF spectrum while substantially reducing interference
NY, USA: Saelig Company, Inc., (Saelig) (www.saelig.com)
has introduced the Kaltman Invisible Waves RF-ResQ™ (Receiver Enhancement System) - an eight-channel
antenna signal processor that can open up portions of unusable RF spectra, while substantially
reducing channel interference. Working with industry standard antennas and with both analog
and digital wireless microphones in the 470 MHz to 928 MHz range, this solution
solves many of the RF congestion issues that plague the professional audio industry.
Housed in a rugged 1U rackmount unit, the RF-ResQ is a standalone wireless microphone filtering
system employing multiple military-spec, high-Q band-pass digital filters. RF-ResQ cleans
up the received RF spectrum, allowing for closer adjacent channel spacing, potentially doubling
available channel counts. It removes intermodulation effects, and improves the reception of
weaker transmissions. Each receiver only sees its assigned transmitter frequency, with no
out-of-band RF interference to weigh down and de-sensitize the receiver's input. Simply installed
between the antennas and receivers, the RF-ResQ's digital signal processing actively shapes
and boosts each antenna's signal for improved performance, yielding an increased wireless
channel population within a crowded wireless space.
The RF-ResQ uses DSP techniques to create filters with Q-values of over 6,000 in the UHF
bands employed by professional audio wireless applications. This 'cleans-up' the received
RF spectrum, allowing for closer adjacent channel spacing and potentially doubling the available
channels with no compromise in power. The DSP operations occur in nanoseconds, so latency
is never an issue. Each channel also includes up to 10 dB of amplification, improving
the reception of weaker transmissions and avoiding the need for amplified antennas. The RF-ResQ
pre-filters the antenna A/B signals at the IF stage for fastest, accurate, and quiet antenna
switching. This enhanced diversity technique means that there is no need for a two-antenna
connection at the receiver input.
The RF-ResQ can be remotely controlled via a network or USB, but once the desired parameters
are set up, it can be locked and left alone, making it ideal in many fixed installation applications.
It can also function as an 8-channel antenna distribution amplifier, with an RF router that
adapts its filters to a variety of receiver and distribution configurations.
Designed and made by Kaltman Creations, the RF-ResQ is available now from Saelig Co. Inc.
