JRE HDMI-2          Dual HDMI 1.4 Filtered Interface                $849


Easily test all HDMI devices in an RF Shielded test environment!  Innovative new Patent Pending design is NOT a low pass filter - which can impact data signals!

  • Fully HDMI compliant with ver. 1.4 including Ethernet

  • Patent Pending design utilizes new approach to filtering high speed data signals

  • Unique ability to discern between Data and unwanted signals

  • Does not low pass filter or impact the HDMI signal

  • 80 db isolation in test system from 50 MHz to over 6 GHz

  • Rugged machined aluminum construction

  • Works with ANY enclosure or screen room

The HDMI-2 filter consists of two independent HDMI ver.1.4 compliant filters inside a machined aluminum housing which provides exceptional RF shielding on all data and power lines.

The  JRE HDMI-2 filter operates on an entirely new principle in data signal filtering. Previous filter designs used low pass filtering on the data lines to attenuate interfering wireless RF signals - however, as data speeds have increased, the data signals fall within the same frequency range as the interfering signals. Thus, simple low pass filtering cannot be used since such a filter will attenuate both the data and the interference.  

Our Patent Pending design uses an innovative application of signal phasing techniques and topology to filter out all RF signals except for the desired data signals. This ability to discriminate between data signals and undesired RF signals is especially valuable when testing at HDMI signal rates, since the signaling rate falls within wireless signal frequencies. Low pass filtering of the HDMI signal is not possible, since the 'stop band' of the filter has to be placed above the range of interfering signals - thus they passed through unattenuated. Previous to the introduction of the JRE HDMI-2 interface, non filtered, but shielded HDMI bulkhead connectors were used. Filtering was non-existent and depended simply upon the HDMI cable shield. Obviously, this 'lash-up' was extremely leaky, especially at higher RF frequencies. The JRE HDMI-2 and its patent pending design completely answers these issues.

Fully HDMI version 1.4 compliant, including Ethernet, ARC, CEC, HEAC. The filter 'appears' to the devices as just a two meter long HDMI cable.

The HDMI filtered interface consists of balanced pairs of data lines utilizing JRE proprietary signal phasing techniques, along with appropriately filtered lines for the control and low frequency conductors. Standard HDMI Type A connectors are used allowing simple and reliable connection to your HDMI devices. The filtering passes the HDMI signal data while providing rejection of 80 dB to undesired RF wireless signals. Included are two HDMI Type A Male to Male jumper cables.

Tight RF shielding to the enclosure wall is assured by the use of a series of 4-40 size mounting screws (template included for stand alone installation). Tests made on competitive filters utilizing a single hole mount with large securing nut were prone to leakage since the coarse thread pitch does not allow a reliable flat seat against the enclosure wall. Additionally, the single mechanical point of securing the filter is subject to loosening and even a tiny loss of tightness results in leakage. Our specifications are measured with the filter installed in an enclosure - and with the same reliability no matter how many times connectors are inserted or the filter bumped or jostled. The smaller size also allows more filters on the I/O plate.
