KESTX02

The KESTX02 is a single chip ASK (Amplitude Shift Key) transmitter IC. It is designed to operate in a variety of low power radio applications including keyless entry, general domestic and industrial remote control, RF tagging and local paging systems.

The transmitter offers a high level of integration and performance, which enables the harmonic rejection and fundamental power requirements of the FCC part 15, and other governing bodies, to be met.

The basic architecture utilises a crystal reference oscillator, an integrated frequency multiplying PLL and a power output stage. Particular emphasis has been placed on low current drain, including a powerdown feature which greatly increases battery life.
