Application and selection notes
Frequency, bandwidth and performance depend on the module and options. Each specification applies only to its listed frequency range and test conditions. PXIe modules require a compatible chassis, controller and software.
WLAN and 5G NR EVM figures apply to the listed bandwidths with RF input and output directly connected, not to every configuration or frequency.
Product images show configuration examples of 6955BA/C, 6955AC, 6955BA/C+6955-H01 and 6955E, in that order. Modules and options are configured according to the quotation.
Ordering and delivery
Typical MOQ is 1 unit; supply scope, chassis and delivery are subject to the formal quotation.
