A piece of RF Microtech at EXPO 2015

on 5 Jun 2015 in News |

RF Microtech has realized an innovative and high-performance ultra-wide band filter for H3G Spa and MiSE (Ministero dello Sviluppo Economico of Italy). The custom device has been developed for the wireless network at EXPO2015  in Milan and it has been installed on middle of May. It is a low-loss bandpass filter from 80 MHz up to 6 GHz and includes five high-rejection (40 – 60 dB) notched bands at all telephone mobile communication frequencies below 2.5 GHz. The device is used to allow the coexistence of telephone mobile communications and wireless network control antennas in the same...

The 6th CNES/ESA International Workshop on Microwave Filters will be held on  23-25 March 2015 in TOULOUSE , France. Co-organised by CNES (Centre National d’Etudes Spatiales) and ESA (European Space Agency), the International Workshop on Microwave Filters addresses the complete development cycle of Microwave Filters, i.e. from filter synthesis to the manufacturing processes. RF Microtech will present the most recent advances on compact high-performance filters for space application based on TM mode dielectric resonator technology and a low-loss and compact E-band diplexer based on micromachined technology. On the first workshop day RF Microtech will also present a short course on Advances in Miniaturized Pseudo-Elliptic Bandpass Filters. More info on full Workshop Programme and Registration can be found in the IWMF...

H2020 SME Instrument: SPACEFIT project approved

on 19 Feb 2015 in News |

RF Microtech’s project SPACEFIT (SPAce-CompatiblE- Filters_in_dIelectric waveguide Technology) has been approved by EU Commission for the Phase 1 of H2020 Research for SME Programme, SPACE topic. As an outcome of this project, RF Microtech will be able to introduce into the space market miniaturized and low-mass RF filters and multiplexers in L/S bands based on dielectric waveguide resonators. The proposed technology will lead to a drastic reduction of the resonator dimensions and weight (up to 50%) and cost (up to 20%) while maintaining high performances. The devices find application as input or output filters in several satellite mobile communications systems and space programs, such as Galileo, Globalstar and Iridium...

Switched Filter Bank

on 19 Nov 2014 in News |

The design of the four-channel switched filter bank  in the S- and C-band using p-i-n-diode switches is described in a paper published in the October issue of IEEE-MTT Transactions. The paper by F. Gentili, L. Urbani, G. Bianchi, L. Pelliccia, R. Sorrentino is entitled “p-i-n-Diode-Based Four-Channel Switched Filter Bank With Low-Power TTL-Compatible Driver”. Narrowband filters designed on suspended substrate stripline lead to an average Q factor of 580. Spurious responses are suppressed from DC to roughly 19 GHz. The biasing circuit is TTL compatible.  The abstract of the paper is available...
