The HPA 4412A from ND SATCOM is a Power Amplifier that operates from 12.75 to 14.50 GHz. It delivers a TWT output power of more than 400 W with a small signal gain of more than 72 dB. This amplifier has an AM/PM conversion of 6°/dB (at rated output power) and provides a harmonic output suppression of -80 dBc (at rated power). It has an RJ45 Ethernet interface, and all RF parameters can be monitored and controlled directly or remotely. The amplifier has a touchscreen display and intuitive WebUI that enables amplifier and system-level control functions, exportable logs, and measurement data files. It ensures safety and durability with coated electrical components to protect against humidity and dust.
The HPA 4412A is available in a 3RU rackmount enclosure that measures 600 x 483 x 133 mm and has an SMA or N-type input connector and WR75 output waveguide interface. It requires a single-phase AC supply from 100 to 260 V and consumes less than 1.25 kW of power. This amplifier has options for integrated BUC, linearizer, and a redundancy control unit (RCU) or M&C system.
