02 Overview
Choose the JRE USB2-2 when two USB 2.0 devices must stay connected through one filtered housing. Its two USB 2.0-compliant low-pass filters each carry data and power through standard Type A Female connectors. The dual-channel format preserves plate space compared with mounting separate housings.
- Each balanced data-line filter passes up to 480 Mbps of USB 1 or 2 data.
- Data-line rejection: greater than 80 dB from 1 GHz through 6 GHz.
- Power-line filters pass DC power and return between host and device.
- Power-line rejection: greater than 80 dB from 400 MHz through 6 GHz.
- USB-compliant enumeration exchanges test hiccups between devices rather than hiding them behind fiber or media-converter links.
- Multiple included 4-40 screws seat the machined-aluminum housing against the wall for RF performance.
- Two Type A Male to Male jumper cables are included.
- Housing: 3.2" H x 3.2" W x 0.8" D (80 x 80 x 20 mm).
Two filters in one housing saves I/O panel real estate. At $725.00, this is the dual-channel option. If the bench needs only one USB 2.0 connection, the JRE USB2-1 is the better fit.
Which USB filter do I need? The USB 2-1 is a low-pass filter, the right pick at USB 2.0 speeds. The USB 3-1 uses signal phasing for USB 3 SuperSpeed. The USB C-1 puts that same architecture on a USB-C connector. The USB2-2 on this page doubles that low-pass path for two USB 2.0 devices.
