Horizon macro combining
A similar arrangement is used in the Horizon macro , which uses a Hybrid
Combiner Unit (HCU) and Dual stage Duplexed combining Filter (DDF), as
shown in Figure 6-7. The DDF has three input ports together with two internal
RF loads, and therefore does not require the addition of any external load.
