ORDERING INFORMATION

KESTX01/IG/MPAD (Tape and Reel)

KESTX01/IG/MPAS (Tubes)

The KESTX01 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 per-

formance, which enables the harmonic rejection and funda-

mental power requirements of the ESTI 300 220, and

other governing bodies, to be met.

The basic architecture utilises a crystal reference oscilla-

tor, an integrated frequency multiplying PLL and a power

output stage. The design is centred around the popular

433.92MHz operating frequency and particular emphasis has

been placed on low current drain, including a power–down

feature which greatly increases battery life.
