HS4456 covers the frequency range from 300 MHZ to 450MHz. Its exquisite design,simple to use, a single chip can achieve “data input,antenna output”system funtion. It has outstanding advantages in transmission power, operating voltage and operating temperature. When the external load is 50Ω, the output power can reach up to +13dBm, which can meet the requirements of many small transmission systems. The operating voltage ranges from 1.8 to 3.6V, and  when batteries supplies, it can ensure that most of them can still be used normally before the power is completely exhausted ; The normal operating temperature ranges from -40℃ to 85℃.

The data is modulated by ASK/OOK UHF with the highest bit rate of 10KBps. Only external crystal oscillator and less components are needed.
