Direct Connections to the mmWave Transceiver
System
The mmWave Transceiver System is a precision RF instrument that is sensitive to ESD and
transients. Ensure you are making proper direct connections to the mmWave Transceiver
System to avoid damaging the device.
Notice
Apply external signals only while the mmWave Transceiver System is
powered on. Applying external signals while the device is powered off may cause
damage.
To prevent possible damage to the device, use caution when connecting signal sources and RF
antennas directly to the TX LO1, TX IF OUT, RX LO1, and RX IF IN connectors of the
mmWave Transceiver System. Operators, technicians, and all other users should ensure they
are properly grounded when manipulating cables or antennas connected to the mmWave
Transceiver System TX LO1, TX IF OUT, RX LO1, and RX IF IN connectors.
If you are using noninsulated devices, such as a noninsulated RF antenna, ensure the devices
are maintained in a static-free environment. If you are using an active device, such as a
preamplifier or switch routed to the mmWave Transceiver System TX LO1, TX IF OUT,
RX LO1, and RX IF IN connectors, ensure that the device cannot generate signal transients
