Hughes Electronics developed a series of Low PIM (≤-160dBc) AISG Smart Bias-Tee’s with 4.3-10 connectivity and IP67 rating. Leading the market in performance, their compact design is especially appreciated in applications where space is at a premium. 7/16 (DIN) connectivity is also available upon request.
What is a Bias Tee?
In the past, connecting AISG controllers to ALDs (Antenna Line Devices) required a discrete data cable, but this results in added installation costs and higher tower leases. Because modern base station radios have integrated AISG controllers, the AISG signal can be combined directly onto the main RF feeder line.
Hughes' AISG Smart Bias Tee facilitates the link between the feeder line and ALDs discarding the long AISG data cable run of a cell site tower by digitally injecting (or piggy-backing) power and RET control signals onto an existing RF feeder cable run.
In Passive technology, it’s the details that matter, Hughes pay attention to those details!
