The SX1243 is an ultra-low-cost, fully integrated FSK or OOK transmitter suitable for operation between 310 and 450 MHz, 860 and 870 MHz, as well as 902 and 928 MHz.

Semtech SX1243
It contains a frequency synthesizer which is a fractional-N sigma-delta PLL. For frequency modulation (FSK), the modulation is made inside the PLL bandwidth. For amplitude modulation (OOK), the modulation is performed by turning on and off the output PA.

The frequency reference used by the PLL is generated by a 22, 24 or 26 MHz crystal oscillator, depending on the frequency band of interest.

The Power Amplifier (PA), connected to the RFOUT pin, can deliver 0 dBm or +10 dBm in a 50 Ω load. Each of these two output powers need a specific matching network when efficiency needs to be optimized.
