2.4.2.1 2 and 4 Watt SSPA Connections
The 2 and 4 Watt SSPAs have a Type N, female (50
Ω) connector (J1) at one end for the
Ku-Band input and a WR-75 waveguide isolator and waveguide filter (J2) at the other
end for the Ku-Band output. Also at the input is the M&C control/power cable connector
(J3) for connection to the HPA (J8) connector on the converter unit.
2.4.2.2 8 Watt SSPA Connections
The 8 Watt SSPA has a Type N, female (50
Ω) connector (J1) at one end for the Ku-Band
input and a WR-75 waveguide isolator (J2) at the other end for the Ku-Band output. Also
at the input is the M&C control/power cable connector (J3) for connection to the HPA
(J8) connector on the converter unit. The HPA’s cooling fan is externally connected at J4
at the factory, and this connection should not be removed. Refer to Table 2-8 for pin
