Holtek HT6P20x2T3 300MHz－450MHz ASK发送方案

Holtek 公司的HT6P20x2T3 系列是工作在300MHz~450MHz的 ASK单片发送器，工作电压为2.0V~3.6V，在3.5V工作电压下，发射功率最高可达10dBm。为低成本，小体积、高效能无线产品的最佳方案选择，可应用于非常多样化的无线领域产品。如汽车防盗、机车/电动车防盗、家庭防盗及大门、窗帘、门铃等之应用。本文介绍了HT6P20x2T3主要特性，方框图以及典型应用电路图。

The HT6P20x2T3 is a CMOS LSI encoder designed for remote control system applications. It encodes 24 bits of information and then serially transmits it via the PAOUT pin upon receipt of transmission enable (DATApins: D0~D4) signals. In addition, the device offers various packaging for flexible combination of address/data so as to meet the needs of various applications. Its address/data is transmitted together with the anti-code bits using an RF transmission medium upon receipt of a trigger signal.

The device is a high performance, easy to use, single chip ASK Transmitter IC for remote wireless applications in the 300 to 450MHz frequency band. This transmitter IC is a true data-in, antenna-out monolithic device and offers high performance in terms of power delivery and operating temperature.
