1+1 Tx MHSB (with equal or unequal receiver coupling)
This option consists of two transceivers with the branching unit providing a single
waveguide interface for connection to an antenna (
). This option provides
monitored hot standby (MHSB) operation, which allows the link to continue to operate in
the event of single point equipment failure. Both transceivers are capable of receiving and
transmitting, but the transmission from only one of the transceivers is routed to the
waveguide interface at any one time. This is achieved with an RF switch which is an
integral component of the IRFU. The other transceiver remains on standby waiting to take
over in case of equipment failure. This option is available with equal or unequal receive
coupling, the latter providing a better radio link budget for the primary transceiver, which
is the preferred transceiver. For more details of 1+1 operation, see
