PE4268

www.DataSheet4U.com Product Specification PE4268 Product Description 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. SP6T UltraCMOS™ 2.6 V Switch 100 – 3000 MHz 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: 2fo = -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 Figure 1.
