HM-T SERIES FSK TX MODULE

GENERAL

HM-T series FSK transmission module is specially designed by Hope Microelectronics Co. for replacing

those applications that used ASK technology module already. It used together with HM-R series FSK

receiver module. Due to the benefits from FSK technology, the module is robust to interference, and longer

working distance can be achieved.

FEATURES

1． HIGHLY INTEGRATED, SMALL SIZE

2． HIGH SENSITIVITY, LOW POWER CONSUMPTION

3． FSK TECHNOLOGY, SUITABLE FOR REPLACING ASK MODULES

4． LESS INTERFRENCE, LONGER WORKING DISTANCE

5． CAN BE USED TO REPLACE ASK MODULE W/O THE NEED OF SOFTWARE CHANGE

6． NO TUNING REQUIRED DURING PRODUCTION

MECHANICAL AND PIN DEFINITION

IF DATA pin is idle for more than 70mS, then the module will enter standby mode automatically.

APPLICATION

Pin to pin replace the old ASK module. Special design can be made for more sophisticated applications.
