<p>PCT No. PCT/EP94/01426 Sec. 371 Date Oct. 27, 1995 Sec. 102(e) Date Oct. 27, 1995 PCT Filed May 5, 1994 PCT Pub. No. WO94/27392 PCT Pub. Date Nov. 24, 1994A communication device (1) for computer local networks of the cordless type uses a modulator (MOD) able to perform FSK modulation on the data (DDI) to be transmitted, with optimum characteristics thanks to a digital switch (SW) controlled by the data (DDI) which commutes during transmission between two fixed frequencies received from a quartz oscillator, in association with a filter of the surface acoustic wave type (SAW). The device (1) permits a significant improvement in circuit integration and is simple and of low cost.</p> |
