Phase2 Microwave has a long history of innovation and production in the Tetra and cellular markets. It has also been active in the US homeland security and point to point markets.

For the most part these systems require cavity filters and diplexers which are a Phase2 speciality with production designs dating back more than 20 years.

Tetra and UHF LTE

Phase2 Microwave has a large range of filters and diplexers in the 350MHz to 450MHz range  which includes Tetra and some of the UHF LTE bands. Medium volume production has been ongoing for many years.

Products, Service & Capabilities

 

Cellular and LTE

Phase2 Microwave offers consultancy services to design and develop filters, diplexers and masthead boxes for high volume manufacture by the cellular industry. After proving the design with a low volume prototype run a production data pack is produced to allow the customer to manufacture anywhere in the world. 

For passive devices and LNA's Phase2 will handle the complete package.

For subsystems including HPAs or more complicated electronics Phase2 will collaborate with other leading design organisations.

General and Test Components

Phase2 has a lot of experience in supplying special often highly complex  filters and multiplexers for testing radar and spacecraft systems.

These can also be Low Pim if required.

VHF and UHF Digital TV Systems.

The global implementation of digital TV networks required new filtering solutions. Phase2 Microwave developed a range of high performance VHF and UHF filters and combiners which have been used in a continental roll out.

By careful design, and the use of stop poles, the filters can be tuned across while maintaining a constant bandwidth. Following waveguide multi-channel multiplexer design procedures the combiners used a cable connected manifold design and the dimensions were derived from using circuit theory.  Up to 5 channels were combined, some of which were adjacent, without needing cable length iterations.

Q1213 - DOT Technology Band Pass Filter

 

These bespoke low pim test bench, is to test payload for the space industry, 

which include all of the filtering required to combine the carries and measure

the pim whilst eliminating the carriers from the rx path to such a level that they

no longer influence pim levels being measured.
