Followings represent brief overview of our capabilities please don't hesitate to submit your custom request 
 
 
Filters/Diplexers/Multiplexers
Covering the frequency ranges from 400 MHz to 40 GHz, our filters/diplexer/Triplexer are designed in Chebyshev, Bessel, Butterworth or quasi elliptic functions to respond the most demanding requirement in term of insertion loss return loss and rejection.
 
Couplers
To be used as power sampler or to split the signal in power combining systems, our designs in waveguide and planar topologies cover the frequency ranges from 2.6 to 40 GHz.
 
Adapters
Operate over the full waveguide frequency band from WR-650 to WR-62 waveguide size. VSWR performance of 1.05:1, or better, Is available over moderate bandwidths such as 10%.
 
Terminations
Available for high power application as well as medium power, low power and precision applications.
 
Rotary Joints
Different configurations (in line, U typ, angle, ...) are available. Custom designs are available also upon request
 
OMT's
Ortho-mode transducers (OMT's) represent a key element in the realization of dual polarization antennas, which are currently employed in order to increase the satellite traffic capacity by simultaneously using two different polarizations (usually vertical and horizontal)
 
Ferrite devices
Waveguide circulators are available in the 3.5 to 40 GHz frequency band. Performance includes parameters such as low insertion loss, low VSWR, low level of intermodulation distortion products and high isolation. Typical applications are in channel combination and separation, antenna multiplexing and load isolation.  
 
Dividers/combiners
Divider combiners are available in waveguide and coax configuration.

Hybrid Tee's

Also cald magic Tee. Common applications  include connecting a transmitter and receiver to a pair of fore and aft antennas and balanced mixer operations.

Power Samplers

Sigmaplus offers power samplers that represent a cost effective solution  to monitor power in matched waveguide systems where high directivity is not a concern.
