Ka-Band LEO satellite transmitters based on new high power, high efficiency packaged MMIC amplifier

对卫星下行链路以更高数据速率运行的不断变化的需求导致了ka波段频率的采用和增加使用。该项目旨在为这些高数据速率下行链路开发一种最先进的、完全不需要itar的ka波段发射机。一套GaAs mmic将在插入新开发的新型ka波段放大器模块之前进行设计，制造和封装，用于未来的LEO卫星通信。其目的是开发具有世界领先输出功率（10W）和效率（>30%）的封装HPA和驱动器，这将为在高发射功率下实现最小失真的超线性操作提供途径。新的封装和MMIC组合技术也将探索与最大限度地提高功率和效率的目标。高功率和高效率的目标将产生世界领先的发射机产品，这将为合作者在这个不断发展和竞争激烈的市场中提供明确和明确的市场领先地位。

The evolving requirement for satellites downlinks to operate at higher data rates has led to the adoption and increased use of Ka-band frequencies. This project is aimed at developing a state-of-the-art, completely ITAR-free Ka-Band transmitter for these high data rate downlinks. A set of GaAs MMICs will be designed, fabricated and packaged before insertion into a newly developed and novel Ka-Band amplifier module for future LEO satellite communications. The intention is to develop a packaged HPA and driver with world leading output power (10W) and efficiency (>30%) which will offer a route to ultra linear operation for minimal distortion at high transmit powers. Novel packaging and MMIC combination technique will also be explored with the aim of maximising power and efficiency. The high power and efficiency targets will yield a world leading transmitter product which will offer the collaborators a clear and well-defined market lead in this evolving and competitive market place.
