The module combines full screening with extensive internal filtering for EMC - minimising spurious radiations
and susceptibilities. The KTX2 module will suit wireless control links in applications including car and building
security and secure unidirectional remote process control. Because of the small size and low power
requirement the module is ideal for use in portable, battery-powered devices such as hand-held remote controls
requiring data integrity and high security.
