Space Grade 4W n256 and SOS Down-Link (S-band) HPA
The Space Grade 4W n256 and SOS Down-Link (S-band) HPA is a High Power Amplifier that covers the 2170 – 2290 MHz bandwidth, designed for installation in a 0.2U slice of a CubeSat satellite. Ensuring full compatibility with the latest standards, the amplifier operates within the 5G NTN S-band Down-Link (2170 – 2200 MHz), in full compliance with 3GPP Release 17/18 n256, as defined in 3GPP TR 38.741. The amplifier is provided with a RF input/output SMA connectors and an Omnetics nano-D receptacle for supplying power and serial/SPI digital controlling interface. The amplifier leverages proprietary redundancy technique to extend lifetime and improve in-orbit reliability; furthermore, it embeds an integrated filter to limit out-of-band emissions. The amplifier is manufactured following ECSS guidelines and Certificate of Conformity is released within produced instances. The amplifier 3D models can be provided upon request. The amplifier is delivered with an Interface Control Document and Datasheet, along with the Certificate of Conformity
