Switchable Step Capacitor CXG1407XR Description The CXG1407XR can be selected four kinds of built-in capacitor (1 to 8 pF), or two path. Sony JPHEMT GaAs process is utilized for low insertion loss, high linearity and high Q Factor capacitance with high accuracy. (Applications: Antenna tuning, i.e Felica characteristics) Features ◆ Low insertion loss (internal switch) ◆ Low voltage drive: 2.4 to 3.3 V ◆ High Q Factor, high accuracy capacitance ◆ Robustness against ESD ◆ Small package: 12-pin XQFN (2.0 mm × 2.0 mm × 0.4 mm Max.) ◆ Lead-Free and RoHS Compliant Structure GaAs Junction Gate pHEMT (JPHEMT) MMIC Absolute Maximum Ratings Input voltage Max. Vctl +4 V (Ta = 25 °C) Input voltage Min. Vctl –0.2 V (Ta = 25 °C) Maximum input. 35 dBm (Ta = 25 °C) Operating temperature –30 to +90 °C Storage temperature –65 to +150 °C This IC is ESD sensitive device. Special handling precautions are required. 1 CXG1407XR Block Diagram RF F1 C1 = 1 pF F2 C2 = 2 pF F3 C3 = 4 pF F4 C4 = 8 pF GND1-3 GND4 F5 GND5 F6 GND6 GND4 7 GND 8 CTLA 9 GND1-3 RF GND5 Pin Configuration 6 5 4 3 XQFN-12P PKG GND6 (2.0 mm × 2.0 mm × 0.4 mm max.) 10 11 12 CTLB CTLC CTLD Top View 2 2 CTLF 1 CTLE CXG1407XR Truth Table CTLA L H － － － － － － － － － － CTLB － － L H － － － － － － － － CTLC － － － － L H － － － － － － CTLD － － － － － － L H － － － － CTLE － － － － － － － － L H － － CTLF － － － － － － － － － － L H F1 OFF ON － － － － － － － － － － F2 － － OFF ON － － － － － － － － F3 － － － － OFF ON － － － － － － Note) 1.
