 摘要：研制了一种高集成度的ISM波段微型射频发射器,此发
射器内部结构简单,发射功率高,功耗低,接口简单,易于使用,
它能直接与各种单片机相连接,组成无线测控系统。对其工作
原理和工作方式进行了分析,并对与之相匹配的天线设计进行
了介绍,最后给出了它与PIC系列单片机的接口示例。 |

| Design and Development of a Miniature Low Power RF Transmitter |
| Abstract：The design and development of a miniature,highly integrat-
ed,ISM band RF transmitter are presented.This transmitter features a
simplestructure,high output power,low current consumption and asim-
ple interface.It can be connected with any kind of microcontrollers di-
rectly to build wireless measurement and control systems quickly and
easily.The working principles and functional modes of the transmitter
are described.The output matching and small loop antenna design are
also stated.At last,an example is explored to show how this RF trans-
mitter works with a PIC microcontroller. |
