Abstract

A common transmit module of a programmable digital radio. The common transmit module has a digital submodule which receives a bit stream and produces a modulated intermediate frequency signal, and an analog submodule which receives the modulated intermediate frequency signal and converts the modulated intermediate frequency signal to a frequency corresponding to a specific type of radio function. The digital submodule includes (a) a sequential/parallel instruction set processor for signal processing and control; (b) a reconfigurable format unit which is reconfigurable to produce output signals for transmitting different types of radio functions, and (c) a modulator which receives the output signals of the reconfigurable format unit and produces the modulated oscillation signal. The analog submodule includes (a) a tunable local oscillator that produces a tunable local oscillation signal; (b) fixed local oscillators that produce fixed local oscillation signals; and (c) a mixing unit that receives the modulated intermediate frequency signal, the tunable local oscillation signal and the fixed local oscillation signals, selectively mixes the fixed local oscillation signals with the modulated oscillation signal to produce non-final intermediate frequency signals, and mixes a non-final intermediate frequency signal with the tunable local oscillation signal to produce a final converted signal for transmission at the frequency corresponding to the specific type of radio function.
