Waveguide Filters

The Waveguide Filters are a family of filters characterized by excellent performance and very robust assembly. They are realized by CNC milling process with a very high accuracy and precision.

Waveguide Filter

We can provide such filters in a very short lead-time from analysis of specs to delivery of first samples (6-8 weeks).

Reconfigurable Filters

Tunable Filter

Tunable filter is a mechanically tunable bandpass filter in Ka-band ideal for radio-link and ground-segment SATCOM applications. It is based on a patented tunable concept developed by RF Microtech.

Reconfigurable Filters

Filter Bank

The switched filter banks are a family of microwave devices composed by several filter channels that are alternatively switched. The filters can be based on several technology (distributed or lumped planar technology, coaxial technology, ceramic-loaded technology).

Reconfigurable Filters

Tunable Filter

Tunable filter is a mechanically tunable bandpass filter in C-band ideal for radio-link applications. It is based on a patented tunable concept developed by RF Microtech

Planar Filters

The planar filters are a family of filters characterized by very high compactness. The filters can be characterized by bandpass, stopband, lowpass or highpass filter response.

blank

Planar Filters

The filters can be based on different planar and multilayer topologies: PCB, LTCC, micromachining and alumina thin-film. They can be implemented either as lumped or distributed filters and they can be fixed in frequency or tunable in frequency, if requested.

blank

Planar Filters

The lumped implementation can be based on market-available SMD components or on custom lumped part design (e.g. LTCC or micromachining). Also high-performance custom designs based on lossy or pre-distorted techniques and differential filter are available.

Planar Filters

The RF interface of these filters can be either a connectorized interface or in SMD technology.

APPLICATIONS

RADIO LINK

We develop planar antennas, beam forming networks, microwave filters and passive components for space, avionics, radio links and satellite communication systems, from L/S-bands up to millimeter waves. In particular, portable beam scanning antennas are built to connect people travelling in remote areas and for SatCom On The Move applications.

TELECOMMUNICATIONS

Innovative microwave solutions developed by RF Microtech apply to various markets, not only the more conventional RF, Electronics, Telecommunications but also to industrial markets apparently non connected to the microwave technology.

SPACE

Miniaturized filters, diplexers as well as light and foldable antennas are developed for the space market, that continuously demands for innovative technologies and miniaturized solutions to increase the payload density and reduce its dimensions.

LOCALIZATION AND SENSING

Microwave systems and sensors of physical parameters such as moisture, weight, particles/defects detection and so on, are developed for the real-time control in industrial processes. Typical applications include the pharmaceutical, agro-food, timber industries. In addition, indoor real-time localization and sensing systems are developed for automated factory management and automated warehousing, as well as for stand-off surveillance & security screening.
