Description
The MTX-MT75 FSK/ASK transmitter is designed
for applications in the 315 MHz, 433 MHz, or 868 MHz
bands.
The MTX-75 consists of a PICmicroŽ
microcontroller architecture and a 315/434/868/915 MHz
ASK/FSK RF transmitter. In addition, it features a 4
channel 10-bit analog-to-digital (A/D) converter, one
comparator channel, and 128 bytes of EEPROM memory. |

Key Features
 Frequency range from 290-350MHz, 380-
450MHz, or
850-930MHz
ASK data rate: 0-40 kbps
FSK data rate: 0-40 kbps by crystal pulling
VCO phase locked to quartz crystal reference;
allows narrow band receivers to be used to
maximize
range and interference immunity
Crystal frequency divide by 4 available(CLKOUT)
Low power consumption
- 14 mA transmitting +6 dBm at 434 MHz
- 4 mA transmitting -15 dBm at 434 MHz
- 0.1 uA standby current
Wide operating voltage range: 2.7 - 16V
