Sigmaplus Inc. developed tools and techniques permitting short development cycles for the most demanding specifications in the following technologies:   

Waveguide Filters:

Designed in different topologies (inductive windows, ridge, waffle, metal inset,..) The input/output could be connectors or flanges. We are offering different functionalities:

• Bandpass
• Stopband
• Lowpass
• Transmit reject
• Receive reject
• Harmonic reject

Rugged construction suitable for use in satcom and emerging radio systems, Where High power, high temperature stability and sensitivity are required.

Combline:

Coaxial cavity with capacitive gap allowing compact design at low frequencies. These filters are suitable for the use in the majority of wireless base station of different standard such as:

• PCS
• AMPS
• GSM
• EGSM
• DCS
• MMDS

We are involved also in development program for cositing solutions. 

Dielectric resonator filters:

Using low loss high permittivity puck suspended in metallic cavity, this kind of filter offer the highest Q factor after the superconductivity. This makes the DR filters suitable for use where the sensitivity is paramount.

Microstrip & stripline filters.

We are offering compact design using innovative topology allowing a wide reject band. Which reduce or eliminate the need of low pass filtering.
