Project TBASERDN031029:

Goal: investigate X-band receiver 

Setup:

LCP  --> ODM6 --> CM9  --> SF1  --> J1 Bank A, 1
                  CM10 --> SF2  --> J3 Bank B, 1
                  CM11 --> SF3  --> J5 Bank C, 1
RCP  --> ODM8 --> CM13 --> SF5  --> J2 Bank A, 2
                  CM14 --> SF6  --> J4 Bank B, 2
                  CM15 --> SF7  --> J6 Bank C, 2

Due to missing G8, have to get to SF4 and SF8 via OR1, 2, CM4, 8.

LCP  --> ODM1 --> CM4 --> SF4  --> J7 Bank D, 1
RCP  --> ODM3 --> CM8 --> SF8  --> J8 Bank D, 2

Tune: Bank A,B,C, D to 9000MHz

Bank  LO2
