Micro-C Transformers:

• Flux Coupled (耦合式巴伦)– DC Isolation (隔直)

– Limited to 500MHz (0.3-500MHz)

– Range of impedance ratios (阻抗比1-16)

• Transmission Line (传输线巴伦)– Good low loss performance up to 1GHz (低插损，频率可到3GHz)

– No DC Isolation (通直流)

– Limited to 1:1 and 4:1 Ratios (仅限1:1及1:4)

• The Autotransformer (阻抗变换器)– Good low loss performance (低插损)

– No DC Isolation (通直流)

– Range of impedance ratios (任意阻抗比)

Current Balun(Transmission Line)

Micro-C transformers are impedance matching devices, not voltage-converter /power supply devices

– Types• Flux-Coupled

• Voltage Balun (Transmission Line)

• Current Balun (Transmission Line)

• Autotransformer

– Package Construction

• Ceramic: Premium high performance

• FR4: Economical for high volume applications

• Plastic: Inexpensive budget performance

– Can provide isolation from DC voltages (flux-coupled)

• For electrical safety

• To minimize un-wanted noise

• Baluns: Flux coupled, Transmission line.

• Auto Transformers

• Cores: Low cost, small, good Curie Temp

• Impedance ratio: 1:1 or 1:4 for Tx Line, any n1:n2 step for flux coupled.

• Typical designed and released in 1-2 weeks

(典型样品周期，1-2周)

Micro-C Directional Couplers

• Very similar to 1:4 Tx line transformer,

– Only differences are n1:n2 ratio is not 1:1

– All 4 ports are terminated in Z0

Micro-C Power Dividers

• Best performance, BW, cost.

• 2,3,4,5,6 way parts

• 典型样品周期1-2周 Samples lead time: 2 weeks

Selection Guide:

Micro-C components is designed for 75 Ohm system in CATV application and 50 Ohm system for wireless communication. Typically it is used in CATV head end modules, set-top box, EOC,FTTx amplifier,MoCA,DOCSIS, etc.. Micro-C CATV components are designed with high consistency and low cost for volume usage in mass production. Micro-C offers a lower cost option compare to Mini-circuits Toko Macom Synergy components. Micro-C CATV components include rf balun transformers, splitters, couplers, filters(diplexer&triplexer) which covers a ultra wideband from 0.1MHz to 3GHz. Also we have best RF engineers to support customers.

Power Dividers/Splitters:

Open-header, Coil Carrier and Bobbin
