RFRXD0420RF/IF射频/中频RFID的射频接收器规格书PDF中文资料

RFRXD0420属于RF/IF射频/中频RFID的射频接收器。由微芯科技股份有限公司制造生产的RFRXD0420射频接收器RF 接收器用于接收已调制的射频信号并对其进行解调，然后将数据传送到系统中进行处理。频率范围是 AM、FM、WB、0 Hz 至 64 GHz，数据速率为 250 bps 至 16 Gbps，数据接口包括连接器、I2C、I2S、引脚焊盘、并行、PCB、串行、焊盘、SPI、UART 和 USB。

DEVICE OVERVIEW

The rfRXD0420/0920 are low cost, compact single frequency short-range radio receivers requiring only a minimum number of external components for a complete receiver system. The rfRXD0420 covers the receive frequency range of 300 MHz to 450 MHz and the rfRXD0920 covers 800MHz to 930 MHz.

Features:

• Low cost single conversion superheterodyne receiver architecture

• Compatible with rfPIC™ and rfHCS series of RF transmitters

• Easy interface to PICmicro® microcontroller (MCU) and KEELOQ® decoders

• VCO phase locked to quartz crystal reference:

- Narrow receiver bandwidth

- Maximizes range and interference immunity

• Selectable LNA gain control for improved dynamic range

• Selectable IF bandwidth via external ceramic IF filter

• Received Signal Strength Indicator (RSSI) for signal strength indication (FSK, FM) and ASK demodulation

• FSK/FM quadrature (phase coincidence) detector demodulator

• 32-Lead LQFP package

Applications:

• Wireless remote command and control

• Wireless security systems

• Remote Keyless Entry (RKE)

• Low power telemetry

• Low power FM receiver

• Home automation

• Remote sensing
