There is a multiplier circuit/ PLL in the DBS-RX. Whatever phase

by this upconversion to be used at LO in the DBS-RX. You cannot get
low phase noise oscillators and high performance mixers in that small
a package. Together these considerations imply more power and
territory and thermal control than is available with the DBS-RX.

Indeed, the target application space of the MAX2118 (satellite TV), upon
which DBS_RX is based, has relatively sloppy
phase-noise requirements.
