The SP12T PE426171 switch features 12 fully-symmetrical transmit ports that give designers the flexibility to freely configure any combination of ports for any mode, and any band, through the bi-directional, two-wire serial-bus control interface. Both of the new switches are MIPI compliant, and have a wide supply range of 2.3 to 4.8 V for operation from VBAT, as well as high ESD tolerance of 4 kV Human Body Model at the ANT port, and 2 kV all pins. Both switches also include an on-chip SAW filter over-voltage protection.
In addition to eight symmetric TX ports, the PE426161 switch features two Super TX (STX) ports that each support low insertion loss of 0.20 dB at 700 MHz, and 0.55 dB at 2690 MHz. The eight symmetric TX ports feature low insertion loss of 0.35 dB at 900 MHz, 0.45 dB at 1900 MHz, and 0.60 dB at 2690 MHz. All 10 TX ports give designers the flexibility to freely configure any combination of ports for any mode and any band through the bi-directional two-wire serial-bus control interface.
The high-isolation PE426171 switch supports four LTE bands, six UMTS bands and four GSM bands, with co-banding applied. This switch has low insertion loss of 0.35 dB at 900 MHz, 0.45 dB at 1900 MHz, and 0.60 dB at 2690 MHz; and high isolation of 38 dB at 900 and 1900 MHz, on all paths.
“These low-loss, flip-chip switches address industry demands for linearity,” said Dylan Kelly, vice president of Peregrine Semiconductor’s Mobile Wireless Solutions business unit. “The PE426161 switch meets the critical Band XIII 2fo requirement which is necessary for LTE network co-existence with GPS.”
