HT9831 -- 315/433MHz ASK Transmitter
General Description
The HT9831 is a highly integrated ASK transmitter IC for remote wireless applications in the 300 to 450MHz frequency band. This transmitter IC is a true "data-in, antenna-out" monolithic device making it very easy for users to implement a wireless system. It is only necessary to supply a crystal generated reference frequency, which is the RF carrier frequency divided by 32, and a few additional external parts to create a complete and versatile transmitter. The HT9831 is capable of delivering +9.5dBm into a 50ohms load. This power level is possible due to a small form factor transmitter (lossy antenna) which can operate near the maximum transmission regulation limit.
