YTX300H/YTX300

ISM TransceiverModule With +20dBm(100mW) Output Power

(The purpose of this YTX300H/YTX300 SPECcovers mainly for the hardware and RFparameterinfo of the module,For software infoplease refer toYX300 chip datasheets anddemo program of YTXDuino (rm) Develo -pmentKit)
1. General introduction
YTX 300H/YTX300module series’ design is based on thehigh performanceCMOSTEK NextGenRF TM YTX300chip, ltoperate at 433/868/915MHz ISM band , The lowreceive sensitivity(-120dBm)coupled with +20dBm(YTX300H)/+13dBm(YTX300)output power ensuresextended range and improved link performance.

2. Features:
140dB maximum link budget.
Low RX current of 7mA.
+20 dBm output power @YTX300H;+13 dBm output power @YTX300Programmable bit rate up to 300 kbps@FSK/40 kbps@OOK
High sensitivity: down to -120dBm.
FSK, GFSK, and OOK modulation.
SMD Package (16x16X1.8
3.Application:
Meter Reading
Wireless data collection
Home automation and
