180° Hybrid
Similar to a 90 degree hybrid but depending on which input port is terminated (called sum & difference ports) the output can be in phase or 180 degrees out of phase.
90° Hybrid
A 90 degree hybrid is a type of splitter with the characteristics of a 3dB directional coupler whose branch line […]
Bandpass Filter
The selection of one frequency band to the exclusion of all others at the input of a receiver, immediately following the antenna.
Cavity filter
Cavity filters are used to pass specific frequencies (the pass band) whilst rejecting others, they have low insertion loss and […]
Cavity power splitter
Used in in-building distributed antenna systems (DAS) to provide equal distribution of power throughout the network.
CEMFAW
The Control of Electromagnetic Fields at Work Regulations 2016, UK legislation that applies to all employers ensuring they perform an EMF risk assessment and depending on the results take appropriate action.
Chip Capacitor
A capacitor is a device that stores energy in the electric field between two closely spaced plates. RF / microwave […]
Circulator
Typically a 3 port ferromagnetic device that circulates an input signal around its 3 ports.
Coaxial Components
A general term to describe components like attenuators, couplers, dividers, terminations etc. that typically have N-Type, SMA or 2.92mm connectors to enable connection via coaxial cable.
Coaxial Fixed Attenuator
RF & Microwave attenuators are used in transmitters, receivers and test & measurement to absorb power.
Coaxial Switch
See Electromechanical RF Switch (& PIN Switch).
Crystal Filter
A filter passes some frequencies but blocks or attenuates others. A crystal filter employs the piezoelectric properties of a quartz […]
