The hmc835 v04.1113 figures 12 and 13 says:
Single-Ended Output Power LO1_N, LO2_P ...
This is consistant with 2.23 Reg 17h Modes Register which says:
[8] R/W Enables Single-Ended output mode for LO1 output 1- Single-ended mode, LO_N pin is enabled, and LO_P pin is disabled 0- Differential, both LO_N and LO_P pins enabled
[9] R/W Enables Single-Ended output mode for LO2 output 1- Single-ended mode, LO2_P pin is enabled, and LO2_N pin is disabled 0- Differential mode, both LO2_N and LO2_P pins enabled
However Table 2 "Pin Descriptions" says:
18 LO2_P RF Output LO2_P, positive side, used for differential or dual outputs only.
19 LO2_N RF Output LO2_N, negative side, used in single-ended, differential, or dual output mode
26 LO1_N RF output LO_N, negative side, used for single-ended, differential, or dual output mode
27 LO1_P RF output LO_P, positive side, used for differential or dual outputs only.
So according to "Pin Descriptions" LO1_N and LO2_N are the outputswhich are single-ended capable.
If I'm running LO1 in differential mode and LO2 in single-endedmode is the SE output on LO2_P or LO2_N ... the documentation seemsto contradict itself.

In SE mode you must use LO1_N (pin 26) and/or LO2_P (pin 18). The descriptions in Table 2 should read...
Pin 18 "RF Output LO2_P, positive side, used in single-ended, differential, or dual output mode"
Pin 19 "RF Output LO2_N, negative side, used for differential or dual output only"
