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
