Triple-Band Concurrent Reconfigurable Matching Network

Reconfigurable Matching Networks (RMN) have found a wide range of applications, such as antenna impedance matching (Antenna Tuning Units -ATU-), the design reconfigurable power amplifiers, applications in Magnetic Resonance Imaging (MRI), adjustable low noise amplifier design, etc. In this paper, we propose experimental and verification synthesis network that can simultaneously work three different bands is completely independent so variations frequency band are approximately transparent to rest. The variable elements used paper varactors. To verify its operation, it applied process laser modulator for C-RAN (Cloud Radio Access Networks) applications. Experimental results demonstrate, expected, losses may depend on state which they driven. Consequently, guarantee good match could also imply greater losses, leading certain trade-off. application genetic algorithms context points out be convenient optimize insertion complete chain instead return losses.
