A compact balanced-to-balanced diplexer composed of two balanced bandpass filters is proposed in this letter. The balanced filters are implemented using compact edge-coupled square split-ring resonators. The design methodology is based on the standard coupled-resonators filter synthesis procedure.

The procurement, evaluation, screening and lot acceptance of RF devices in leadless SMD packages to be used in spacecraft applications show unexpected difficulties whenever degolding or retinning processes are required. This is associated with the induced lack of coplanarity in the contacts after those.

Surface contamination involving micrometric particles, microbiological agents, molecular adsorbate and others, represent a significant hazard in many areas of industry. For instance, high-level cleanliness is a critical requirement that any EEE device has to fulfil at any development stage: from the fabrication process of single components, before encapsulation, to the final PCB assembly.

Passive liquid crystal (LC) devices are becoming an interesting alternative for the manufacturing of photonic devices in spatial applications. These devices feature a number of advantages in this environment, the lack of movable parts, and of exposed electronics being among the most outstanding ones.

Many basic testers available which offer the capability to carry out a test in a rather short delay (a few weeks) at a relatively low cost. Capability to develop on-demand test setup for complex devices (μP High-frequency devices, RF fixtures etc…) higher cost driven by the test preparation effort.

High brightness semiconductor lasers are potential transmitters for future space lidar systems. In the framework of the European Project BRITESPACE, we propose an all semiconductor laser source for an Integrated Path Differential Absorption lidar system for column-averaged measurements of atmospheric CO2 in future satellite missions.
