Objective: This activity shall design and test two diplexer compatible for seamless integration with Outdoor Units.
Targeted Improvements: Enabling technology to allow antenna sharing of two frequency bands compatible with monolithic circuit fabrication.
Multi-band user terminal capability is a requirement which is typical of global mobile access (e.g. maritime, aeronautical) or fixed services where High-Throughput Satellites (HTS) internet access is combined with DTH reception. These scenarios indeed mandatecombined operation at Ku and Ka-band. This requires updated electronics and an antenna reflector tuned to both Ku- and K-/Ka- band frequencies. In such systems, a low loss and low cost diplexer is a key component enabling two RF chains to share a common antenna. Low-loss RF components are currently designed in waveguide technology. This has inconveniences in terms of size, weight, cost, incompatibility with monolithic circuits and increased fabrication complexity at the higher frequencies.
This activity aims at developingtwo diplexer prototypes using novel technologies, aiming at large-scale fabrication of RF filters compatible with planar monolithiccircuits. Particular emphasis shall be devoted on Micromachining, Low-temperature Co-fired Ceramic (LTCC), and Substrate IntegratedWaveguide (SIW) technologies, which have recently demonstrated high Q-factor and cost effective up to the millimetre-wave range.
