Peregrine introduces its highest-linearity switches for 4G LTE

At this week’s 2012 IEEE MTT-S International Microwave Symposium (IMS) in Montreal, Canada (17-22 June), Peregrine Semiconductor Corp of San Diego, CA, USA, a fabless provider of radio-frequency (RF) integrated circuits (ICs) based on silicon-on-sapphire (SOS), announced its highest-linearity switches for 4G LTE applications.

• The HaRP technology-enhanced SP10T PE426161 switch meets the second-harmonic (2f0) requirement of -80dBm for Band XIII, making it the highest-linearity switch in the Peregrine portfolio. In addition to eight symmetric TX ports, the PE426161 switch features two Super TX (STX) ports that each support low insertion loss of 0.20dB at 700MHz, and 0.55dB at 2690MHz. The eight symmetric TX ports feature low insertion loss of 0.35dB at 900MHz, 0.45dB at 1900MHz, and 0.60dB at 2690MHz. 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 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. 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 0.35dB at 900MHz, 0.45dB at 1900MHz, and 0.60dB at 2690MHz; and high isolation of 38dB at 900 and 1900MHz, on all paths.

Both switches are MIPI compliant, and have a wide supply range of 2.3-4.8V 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 also include an on-chip SAW filter over-voltage protection.

The PE426161/71 switches are available in a flip-chip package. Samples and volume-production quantities can be ordered through Peregrine’s global direct sales management.

“These low-loss, flip-chip switches address industry demands for linearity,” said Dylan Kelly, VP 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.”
