pSemi推出ub-6 GHz射频开关

 

 

New pSemi Sub-6 GHz RF Switches Enable Hybrid Architectures in 5G Massive MIMO Base Stations

 

SP4T Switches Deliver Industry-leading Performance for

Hybrid Beamforming Systems

 

pSemi® Corporation, a Murata company focused on semiconductor integration, expands its portfolio of RF SOI switches targeted for the latest 5G wireless infrastructure and massive MIMO base station deployments. By using the new high linearity switches in hybrid architecture topologies, base station designers can save valuable board space and improve thermal management, reducing the overall system’s cost, weight and power consumption. pSemi’s advanced SP4T switches deliver best-in-class linearity, insertion loss and power handling performance to improve spectral efficiency in sub-6 GHz active antenna systems.

 

 

Two back-to-back pSemi SP4T switches with selectable phase shifts enable the analog beam control utilized in hybrid beamforming architectures. This phase shifter topology improves antenna beam steering and control in active antenna systems.

 

High Linearity RF Switches Features & Benefits

 

Covering a frequency range of 1.8 to 5 GHz, each UltraCMOS® PE42443 and PE42444 switch delivers industry-leading RF performance across the n41, n77, n78 and n79 bands. Available in two pin-to-pin compatible configurations, the PE42443 (negative and positive supply voltage) and the PE42444 (positive supply voltage only) are offered in 4 x 4 mm LGA packages.

 

·    Spectral efficiency — High linearity and high power handling maximizes data throughput.

·    Energy conservation — Low insertion loss improves overall system efficiency.

·    Flexible beam management — Fast switching speed supports symbol-level analog beam adjustments to enable massive MIMO systems.
