8. A13 RF Front End Assembly
High Band #2 RF signal path utilizes a high band mixer internal to the A13 RF Front End
Assembly for RF input frequencies from 13 GHz to 26.5 GHz. Since all the control voltages and
biasing were already fully tested, failures from 13 GHz − 26.5 GHz will most likely be caused by
the A13 RF Front End Assembly. If the failure is amplitude related, proper adjustments such as
frequency response and the YTF Preselector adjust should be performed first before changing
the A13 RF Front End Assembly. Refer to
In order to gain access to the front end components, remove the side chassis
