Wireless RF Test Enclosures
Rainford PTC — JRE USB 2.0 High Speed Filtered Interface
Easily test all high speed USB 2.0 devices in an RF Shielded test environment.
 Simple single 1 inch hole mounting
 Features two USB 2.0 RF filtered interfaces
 Over 80 dB attenuation beyond 1 GHz
 Rugged machined aluminium construction
 Balanced filtering for minimal ringing
 Excellent RF Isolation
The USB EMI Filter consists of two sets of high speed USB 2.0 ports.
Each USB port is designed to reject frequencies greater than 1 GHz
while passing data and power between a host computer on one side
and a USB device on the other. The USB interface consists of a bal-
anced pair of bi-directional data lines and an unbalanced power and
return pair. Each output cable is 4 inches (Min.) long. The USB cable
and connectors have the standard USB 2.0 pinout and configuration.
The data line filters pass the up to 480Mbps of USB Type 1 or 2 data
while providing rejection greater than 80 dB from 1 GHz through 6 GHz.
The power line filters pass the DC power and return while providing
rejection greater than 80 dB from 1 MHz through 6 GHz.
