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. A Colpitts crystal oscillator is used as the reference oscillator of a phaselocked loop synthesizer. The VCO's output signal feeds the power amplifier.
Key Features
Fully integrated PLL-stabilized VCO Frequency range from 250-350MHz, 380450MHz, or 850-930MHz Single-ended RF output FSK through crystal pulling allows modulation from DC to 40 kbit/s High FSK deviation possible for wideband data transmission ASK achieved by on/off keying of internal power amplifier up to 40 kbit/s Very low standby current On-chip low voltage detector High over-all frequency accuracy FSK deviation and center frequency independently adjustable
