The CX4 is a compact single active, dual output amplifier. The amplifier stages are based on extremely high performance GaN solution that makes the usable gain range especially wide and allows for high output level. The amplifier comes in two variants, a Group Amplifier CX4-DG and an End Amplifier CX4-D. Both variants can be equipped with an HMS transponder, allowing for remote control of features such as Ingress Switches and Power Save. Alignment can be done using electronic circuits controlled with push buttons. A high gain return amplifier circuit is fixed on the motherboard. The amplifier is remote powered and features a combined RF and AC bypass port next to the input port.
