MTX-705/15/35
FSK/ASK TRANSMITTER MODULE
The MTX-705/15/35 FSK/ASK transmitter is designed for applications in the 315 MHz, 433 MHz, or 868 MHz industrial-scientific-medical (ISM) band, according to the EN 300 220 telecommunications standard; but it can also be used in any other country with similar frequency bands. The MTX-705/15/35 transmitter consists of a fully integrated voltage-controlled oscilattor, a divide-by-32 divider, a phase-frequency detector and a charge pump. An internal loop filter determines the dynamic behavior of the PLL and suppresses reference spurious signals.
