High Precision T/R-Module for SAR Earth Observations

Inhalt:
The paper will discuss the design, the main features and the measured performance of a T/R-Module for a Synthetic Aperture Radar. The internal temperature drift compensation over a wide temperature range as well as low noise amplification during receive operation are the key features of the module including polarisation agility and high gain- and phase accuracy. The module is a qualified product. The 'Standardised Modular T/R-Module' (SMTR-Module) is the core unit together with two further physical building blocks 'Front-end Electronics Unit' and 'Control Electronics', all of them assembled in a common housing.
