    • Low Insertion Loss
    • High Port-to-Port Isolation
    • GPIO Interface for 1.3 V to 2.7 V Control Logic
    • Broadband Performance Suitable for All Cellular Modulation Schemes up to 8.25 GHz
    • Very Low Current Consumption
    • Linearity and Harmonic Performance Ideally Suited for LTE Applications
    • DC blocking capacitors are not required in typical applications

    The QM11022A is a dual-pole double-throw transfer switch designed for general purpose switching applications where RF port transfer (port swapping) control is needed. The low insertion loss along with excellent linearity performance makes the QM11022A ideal for multi-mode GSM, EDGE, UMTS, and LTE handset applications. The RF ports can be directly connected in 50 ohm systems and control logic is compatible with 1.3 V to 2.7 V systems. The supply voltage is intended for connection to 2.8 V systems but the device is operable from 2.4 V to 5.5 V. The compact 1.1 mm x 1.5 mm size offers mobile handset designers an easy-to-use switch component for quick integration into multimode, multi-band systems.
