PE42452数据手册RF/IF射频/中频RFID的射频开关规格书PDF

描述 Description

The PE42452 is a HaRP™ technology-enhanced absorptive SP5T RF switch designed for use in 3G/4G wireless infrastructure and other high performance RF applications.
This switch is a pin-compatible upgraded version of the PE42451 with 1.8V control logic. It is comprised of five symmetric RF ports and has very high isolation. An integrated CMOS decoder facilitates a three-pin low voltage CMOS control interface and an external negative supply option. In addition, no external blocking capacitors are required if 0V DC is present on the RF ports.
