SKY12245-492LF数据手册RF/IF射频/中频RFID的射频开关规格书PDF

描述 Description

The SKY12245-492LF is a compact, integrated high-powersingle-pole, double-throw (SPDT) PIN diode switch with drivercircuit for TDD-LTE and similar applications. The part operateswith a single +5 V supply and switches with a single controlvoltage (0 to 3 V). It can be tuned to specific RF bands within therange of 0.3 to 4.2 GHz by modifying select external SMTcomponents.This device features low TX and RX insertion loss, high isolationwith low DC power consumption and requires minimal externalcomponents, enabling a smaller PCB footprint.The device is provided in a 5 x 5 mm, 20-pin Quad Flat No-Lead(QFN) package.
