Two frequency range radio frequency digital word transmission having input stage/antenna/amplifier and digital signal controlled multiplexer with phase locked local oscillator two mixers feeding.

摘要

The digital word transmitter has an input stage with an antenna (8) and an amplifier (9) with a multiplexer (MUX) controlled by a digital signal (C) for reception and transmission. There is a three port mixer (M1), and a local oscillator (LO), with a phase lock loop. There is transmission to a second mixer (M2) and the first mixer, allowing transmission and reception over a wide frequency band.
