UMS launch the 2 first products of its new family range: the highly compact 1 to 3-way Wilkinson Power Divider Combiner (WPD).

Extremely compact, UMS Wilkinson Power Divider Combiners (WPDs) help develop reduced-size systems taking advantage of integrated WPDs instead of PCB layout divider/combiner design. They are dedicated to onboard Telecommunications & Radars systems, portable Test & Measurement systems, and high channel density compact Radar & Communication systems. They exhibit very low insertion loss, good isolation, and good matching with low magnitude and phase unbalance. UMS proposes 1 to 3-way Power Divider Combiners. The 2 first products are proposed in a low-cost 3x3 QFN package.

They are mainly dedicated to customers developing MIMO antenna where multiple Tx / Rx chains need dividers and combiners on RF signal paths. They are therefore highly matching the requirements of 5G and Satcom radios solving high-density PCB issues thanks to small-footprint SMDs. Last but not least Test and Measurement strongly benefit compact WPDs in RF multi-channel paths for 5G and Satcom testing systems in development & production.

The 2 first products launched by UMS are 1:3 way in the QFN package. UMS will also soon propose a 1:2 way in the DFN package.

CHW4213-QAG

The CHW4213-QAG is a 3-way 15-25GHz Power Divider Combiner manufactured on a UMS proprietary GaAs passive technology. It exhibits an excellent insertion loss of 0.5dB and a good isolation range of around 20dB. It exhibits a very good a very good amplitude unbalance <0.5dB and unbalance phase < +/-2°.

●Broadband performance: 15-25GHz

●Insertion loss: 0.5dB

●Isolation: 20dB

●Good amplitude unbalance: <0.5dB

●Good phase unbalance: <+/-2°

●QFN package 3X3

●MSL1

CHW4313-QAG

The CHW4313-QAG is a 3-way 24-35GHz Power Divider Combiner manufactured on a UMS proprietary GaAs passive technology. As the CHW4213-QAG, It exhibits an excellent insertion loss of 0.6dB, a good isolation range of around 20dB. It exhibits a very good amplitude unbalance +/-0.5dB and a very good unbalance phase -5°.

●Broadband performance: 24-35GHz

●Insertion loss: 0.6dB

●Isolation: 20dB

●Good amplitude unbalance: +/-0.5dB

●Good phase unbalance: -5°

●QFN package 3X3

●MSL1

This commercial circuit is facing no known competition and is setting a new state of the art.
