Insertion Loss versus Frequency Figure 16. Input Return Loss versus Frequency APPLICATIONS INFORMATION DESIGN INFORMATION The MRFIC0903 SPDT antenna switch was designed for low cost, flexibility and ease of use. This is accomplished by its internal topology that allows control of the switch through its TTL/CMOS compatible (0 to VDD) control pins. Operating on a single positive supply, the switch was designed for a minimum supply voltage, minimum power consumption and low current TTL/CMOS compatible control signals. Due to the device's inherently low harmonic distortion, the switch requires little harmonic filtering at its outputs. It also has a high reverse third-order intercept point for use in non- TDMA antenna diversity applications (analog cellular systems). BIASING CONSIDERATIONS The MRFIC0903 is based on a floating "cold FET" topology. With this topology, the differential voltage between VC1 and VC2 dictates the power handling capability. For example, the device's power handling capability is the same with the device biased with 5 V at VC1 and 0 V at VC2, with 0 V at VC1 and -5 V at VC2, or with 3 V at VC1 and - 2 V at VC2. POSSIBLE APPLICATIONS The MRFIC0903 can be used in a number of cellular and cordless phone applications. The part is applicable for analog cellular phones in systems such as AMPS, TACS, NAMPS, ETACS and NMT900; for digital cellular phones in systems such as GSM, PDC, DAMPS, DCS1800, PCS and NADC; and for cordless phones in systems such as DECT, PHS, ISM, CT1 and CT2. In general it can fit into any application where high power handling capability is required for frequencies ranging from 100 MHz to 2 GHz. EVALUATION BOARDS Evaluation boards are available for RF Monolithic Integrated Circuits by adding a "TF" suffix to the device type. For a complete list of currently available boards and ones in development for newly introduced product, please contact your local Motorola Distributor or Sales Office. THEORY OF OPERATION The MRFIC0903 can be used as a transmit and receive or antenna diversity switch in the frequency range from 100 MHz to 2 GHz with incident power levels as high as 4 watts. The frequency behavior can be optimized by resonating the DC blocking capacitor's position and value with the parasitic inductance of the package lead. Operation from 300 MHz to 1.6 GHz can be optimized with a high Q 100 pF blocking capacitor. For the higher frequency band from 1.6 GHz to 2.0 GHz, a 8.2 pF capacitor is suggested. Further improvements can be achieved by resonating the inductance of VDD, VC1, and VC2 pins with the appropriate capacitor values. The power handling capability and linearity of the MRFIC0903 is dependent only on the supply voltage. With a 3 V supply, the device handles 1.25 W (1.6 W PEP) of incident power while maintaining good linearity and low harmonic distortion. The power transmitting capability increases to 3 W of incident power with a 5 V supply and up to 4 W with a 7.5 V supply.
