RF1226 BROADBAND MEDIUM POWER DIFFERENTIAL SPDT SWITCH Package Style: QFN, 12-pin, 2.0 mm x 2.0 mm x 0.55 mm Features Broadband Performance Low Frequency to 3.5 GHz Very Low Insertion Loss 0.25 dB Typ at 0.90 GHz 0.45 dB Typ at 1.90 GHz Excellent Linearity Performance IIP2 Typ 109 dBm at 0.90 GHz IIP2 Typ 105 dBm at 1.90 GHz 1.6 V Capable for Low Power Applications Lead Free and RoHS Compliant Applications Cellular Handset Applications IEEE 802.11b/g WLAN Applications Multi-mode GSM, WCDMA Applications WLAN Applications SAW Filter Switching Functional Block Diagram Product Description The RF1226 is a single-pole double-throw (SPDT) differential switch designed for general purpose switching applications which require very low insertion loss and low power signal routing applications. Excellent performance matching between the two SPDT devices makes the RF1226 particularly suited to differential SAW filter switching. The RF1226 features low insertion loss, high linearity, and very good harmonic characteristics. The switch is operable from 1.6 V to 3.6 V control voltage. It is fabricated with 0.5 um GaAs pHEMT process and is packaged in a very compact 2 mm x 2 mm 12-pin leadless QFN package.
