CATV NETWORK PARTS (SMD / RF BALUN TRANSFORMERS)

Product Description

Our Balun coil products were designed in Base/SMD Type Package for
easy mounting into the PCB we are using
Balun Core(RH,RID,TOROIDAL) that can acheive the best efficiency and
the best technical permormance and also are helpful to reduce mounting space of
the PCB for its very dB radiation from the body.
The more thin type or special type depend on customers request is also possible.
additionally,special
(SMD)Balun Transformers,
(SMD)Spliter Coils,
(SMD)RF 4:1 Transformers,
(SMD)75 Ohm Coupler,
(SMD)Micro Balun Transformers,are possible in
Base and SMD type package.
High volume CATV applications.

[SMD 75 Ohm Coupler] Coupler is a high performance 75 Ohm Coupler,in a low cost, surface mount package,
The coupler is designed for use in high volume CATV applications.
Typical applications include Settop Boxes,Network Interface Units,Line Amplifiers and Headend equipment.

[SMD RF 4:1 Transformers]
RF Transformer is a 4:1 transformer in a low cost,surface mount package.
Ideally suited for high volume cellular and wireless applications.
Typical applications include single to balanced mode conversion and impedance matching.
