RF transmitter module 1. Transmission power:25mW 2. Operating current: max:40mA (9V), min:9mA (3V) 3. Factory price
Model No.: DL-T02B
Description: 25mW transmision power RF transmitter module
Product details:
DL-T02B is developed based on DL-T02A, but the size of DL-T02B is smaller and the transmitting distance is longer. Besides, there is the antenna output pin on board in order to get more popular usage. The module has features of small size, easy installation and simple operation. Additionally, this module has processed by electricity-loaded high temperature aging testing.
Application:
a. Transmission for the signals from anti-theft alarm and various digital signal of low rate;
b. Industrial remote control, remote measurement and remote sensing;
c. The remote controls for various home appliances and intellectual toys.

Size and Pin definition
Notes for usage
a. Pls use soft lead wire or other hard metal (like telescopic antenna), the length should be chosen according to the respective frequency (24cm for 315MHz, 18cm for 433.92MHz). The antenna should be stretched as straight as possible if it is using soft lead wire.
b. If put the module inside the metal case, the antenna should be fetched out of case. To connect the metal telescope antenna with 50ohm coaxial line will get better effect in transmission.
c. The power voltage needs to be stable with low ripple factor and multilevel wave filtering (such as adding magnetic ball, inductance, capacitance etc.)
d. As the wireless frequency is precious natural resources, please do not keep the module always at transmission condition.
