AS3933数据手册RF/IF射频/中频RFID的RFID射频接入监控IC规格书PDF

描述 Description

The AS3933 is a 3-channel ASK receiver that generates a wake-up signal upon detection of a data signal with a carrier frequency in the range of 15-150 kHz. It can be used to wake-up active tags in RTLS, PKE and other similar tracking and access control systems.

特性 Features

• Reliable wake-up pattern

• 80µV wake-up sensivity

• Low power listening mode (2.3µA)

• One-, two- or three-channel operation

应用 Application

• Active RFID tags

• Real-time location systems (RTLS)

• Operator identification

• Passive keyless entry (PKE)

• Wireless sensors
