Tunable Radio Frequency (RF) filters are now essential designs in our modern PSME spectrum, these filters provide dynamic frequency selectivity, enabling efficient spectrum management and rejecting unwanted dirty RF signals and interference. These filters selectively allow certain frequency bands to pass while attenuating unwanted signals. Unlike the fixed Bandwidth filtered LPDA antennas, which are designed for a specific frequency band, tunable RF filtered LPDA Antennas offers a greater flexibly to be tuned and operated across multiple bands. LPDA-A-DT V2 is a tunable filter design and operates from 470 MHz to 710MHz covering our industry PSME band for world wide use. One of the most significant advantages of tunable RF filters is their ability to dynamically adjust their frequency range. By selectively attenuating unwanted signals, tunable filters improve signal integrity and reduce adjacent channel signal interference. LPDA-A-DT V2 may be used in active or passive mode to suit individual applications: Narrow-Band Digitally Tuned (DT) mode, tunable in the 470-702MHz with nominal 24MHz bandwidth tunable in 8MHz steps with user adjustable 20dB gain (* optional 48MHz Bandwidth tunable in 12MHz step over 470-710MHz). Fixed Bandwidth – WB Mode in the 470-710MHz range with user adjustable 14dB gain When there is no dc present the LPDA-A-DT V2 can be used as a High Gain Passive Antenna for receive or transmit applications with in-built filtering 470-702MHz, passive gain boasting 5dB. In the Digitally Tuned Mode (DT) the band-pass filter is Narrow-Band RF tuned to 24MHz frequency window to reject all outer frequencies providing an excellent protection to the receiving system, the digitally tuned band pass filter is user tunable in 8MHz steps via the OLED menu from 470 to 702MHz. (*) In the Wide Band Mode (WB), a very low loss Band-pass filter is employed with fixed bandwidth between 470-710MHz. The booster section; the input design uses a digitally adjustable RF-Attenuator before the RF Amplifier against RF overload and similarly the Booster Gain adjust is used after the RF amplifier to compensate long antenna extension cable losses, both are user adjustable. The booster section employs a very high dynamic range Low Noise RF amplifier offering a linear gain within the tuning range. The LPDA-A-DT V2’s unique design offers flexibility as well as additional front-end protection against interfering dirty RF, in DT-Mode the booster offers 20dB user adjustable gain to compensate long antenna extension cable losses hence increased distance between the transmitter and the receivers, LPDA-A-DT V2 finds its application in film making, documentaries, fixed installations as in studios, theatres. Compatible with any UHF wireless receiving systems (Digital or Analogue) providing a directional coverage pattern. The antennae are constructed using advanced multi-layer PCB designs technique with copper-clad epoxy fiberglass to withstand heavy duty use in harsh environments, providing long life and consistent performance under difficult operating conditions. The booster box is a custom-design machined aluminum, black anodized with water resistant O-ring mounting. Mounting is made easy with integrated thread that directly mounts on to a tripod or with the supplied adaptor it can be mount directly on to a microphone stand. Powering is through coaxial cable power source of 10-18Vdc.
