Cavity Splitter

Directional Coupler

Tapper

Hybrid coupler

RF power splitter s can be used to combine and split RF power, the only difference being that RF power is applied to one port and extracted from other in the case of the RF splitter, and for the RF combiner, power is applied in the opposite direction.

Support frequency range

698-2700MHz

698-3800Mhz

A directional coupler is an passive component having 3-port  with one port being isolated from the input port and another as a through output port. The device is normally used to split Directional couplers has wide range of applications for indoor and outdoor

These devices are suitable for use with antennas and leaky cable systems and wireless base stations.

Support frequency range

698-2700MHz

698-3800Mhz

    A RF Tapper is a product to feed or ‘tap’ a portion of the input RF signal to a 2nd port ( output port and tap port ) 

    A Tapper is mostly used as part of a Distributed Antenna System (DAS) – often found in in-building, undergrounds networks.

    Support frequency range

    698-2700MHz

    698-3800Mhz

    Tamagawa 3dB Hybrid Couplers is designed to meet the market requirements of the wireless communication. It combines 2 signal from different source/frequency to a single antenna or distribution antenna system. Get example an in-building application, both outputs can be used to distributes as much as signal to the antenna system. All units are sealed to IP65 specification.

    Point Of Interface

    Modular

    Fix in housing

    With the development of radio technology, frequencies are continuously upgraded according to 3/4 and 5G technologies, the use of Modular POI will make it easier to upgrade in cases where it is necessary to change frequencies.

    compliant with SISO MIMO

    sub frequency 6

    Low insertion lost

    low VSWR

    low PIM

    High Isolation

    For some projects with low adaptability, and the technology upgrade is not too strict, Fix POI is the best choice with low cost and no need for continuous maintenance.

    The device is designed all in one for easy installation and operation

    suitable for 3G/4G/5GNR
