Package Type 20-lead 4x4 mm QFN The PE4268 SP6T RF UltraCMOS™ Switch addresses the specific design needs of the Quad-Band GSM Handset Antenna Switch Module Market. Broadband performance also makes it a versatile solution in other IF and RF applications. The switch includes two high power paths with low insertion loss and four low power paths with high isolation. On-chip CMOS decode logic facilitates three-pin low voltage CMOS control. High ESD tolerance of 1500 V at all ports and no blocking capacitor requirements make this the ultimate in integration and ruggedness. The PE4268 UltraCMOS™ RF Switch is manufactured in Peregrine’s patented Ultra Thin Silicon (UTSi®) CMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS. Product Specification SP6T UltraCMOS™ 2.6 V Switch 100 – 3000 MHz Product Description Figure 1. Functional Diagram PE4268 Features • Three pin CMOS logic control with integral decoder/driver • Low TX insertion loss: 0.55 dB at 900 MHz, 0.7 dB at 1900 MHz • TX – RX Isolation of 48 dB at 900 MHz, 40 dB at 1900 MHz • Low harmonics: 2f o = -84 dBc and 3fo = -70 dBc at +35 dBm input power • 1500 V HBM ESD tolerance • RX SAW over voltage protection circuit • Harmonics immune to RX VSWR • No blocking capacitors required • 20-lead 4x4 mm QFN package |
