BH1415F-E2RF/IF射频/中频RFID的射频发射器规格书PDF中文资料

BH1415F-E2属于RF/IF射频/中频RFID的射频发射器。由罗姆半导体集团制造生产的BH1415F-E2射频发射器RF 发射器用于发送射频信号并调制该信号以承载系统中的数据。频率范围为 315 Hz 至 64 GHz，数据速率为 3 kbps 至 2 Mbps，功率输出为 -30 dBm 至 24.7 dBm。数据接口有连接器、I2C、引脚焊盘、并行、PCB、串行、焊盘、SPI、UART 和 USB，天线连接方式有堡形、板载、PCB 和通孔。

The BH1415F is a FM stereo transmitter IC that transmits simple configuration. The IC consists of a stereo modulator for generating stereo composite signals and a FM transmitter for broadcasting a FM signal on the air. The stereo modulator generates a composite signal which consists of the MAIN, SUB, and pilot signal from a 38kHz oscillator. The FM transmitter radiates FM wave on the air by modulating the carrier signal with a composite signal.

特性 Features

1) It is possible to improve the timbre because it has the pre-emphasis circuit, limiter circuit, and the low-pass filter circuit.

2) Built-in pilot-tone system FM stereo modulator circuit.

3) The transmission frequency is stable because it has a PLL system FM transmitter circuit.

4) PLL data input (CE, CK, DA) by serial input.

Applications

CD changer, Car TV, Car navigation, Wireless speakers, Personal computer (sound board), Game machine
