Non-Isolated Combiners
The most simple technique to combine several amplifiers; the necessary isolation is normally provided by circulators at each input. Absorbing Loads are connected to the circulators.
They can be designed for any number of inputs (typically up to 20 inputs), and according to different architectures (planar, linear, radial). Loads on circulators are all the same power.
COM-TECH can design and manufacture Non-Isolated combiners according to the custom requirements:
- Center Frequency: 100 MHz to 800 MHz
- Number of Ways: 2 to 20
Quadrature Combiners
Based on a cascade of Hybrid Couplers, they allow binary combinations (2, 4, 8 …) of amplifiers. Balancing Loads provide high levels of isolation; load powers increase along the chain, the output load requirement is ¼ of the output power.
COM-TECH can design and manufacture Quadrature combiners according to the custom requirements:
- Center Frequency: 100 MHz to 800 MHz
- Number of Ways: 2, 4, 8, 16
Gysel Combiners
Isolated In-Phase power combiners, can be designed for virtually any number of inputs (practical realization up to 20 ways are possible). Balancing Loads are all the same power. Inputs are radially distributed, making the connections quite complicated.
COM-TECH can design and manufacture Gysel combiners according to the custom requirements:
- Center Frequency: 100 MHz to 800 MHz
- Number of Ways: 2 to 20
