CXG1125ER
High Power 6 x 4 Antenna Switch MMIC with Integrated Control Logic for PDC Full Packet
Description The CXG1125ER is a high power antenna switch MMIC for PDC dual 800MHz and 1.5GHz. This IC is suited to connect 2Tx/3Rx to one of 4 antennas equipped with full packet mode. The CXG1125ER has on-chip logic circuit for operation with 6 CMOS inputs. The Sony's GaAs J-FET process is used for low insertion loss and low voltage operation. Features * Low insertion loss: 0.5dB @900MHz, 0.7dB @1.5GHz * High linearity: Harmonic < - 65dBc * CMOS compatible input control * Small package: 24-pin VQFN (4.0mm x 4.0mm) Applications 6 x 4 antenna switch for digital cellular such as PDC handsets Structure GaAs J-FET MMIC Absolute Maximum Ratings (Ta = 25C) * Bias voltage VDD * Control voltage * Operating temperature * Storage temperature Vctl Topr Tstg 24 pin VQFN (Plastic)
