Abstract
A radio frequency and microwave module for simultaneously transmitting data and audio signal comprises a transmitting unit and a receiving unit. The transmitting unit has two pre-amplifier circuit two voltage-controlled oscillators (VCO), a phase-locked loop (PLL), two low pass filters (LPF) , two amplifiers, a power combiner, a ceramic filter and a transmitting antenna. The receiving unit has a receiving antenna, a ceramic filter, a first low noise amplifier (LNA), a first mixer, an amplifier, a third VCO, a PLL, a low-pass filter, a channel filter, an IF amplifier, a phase shifter, a second mixer, a second low noise amplifier (LNA), a filtering circuit and an operational amplifier. The inventive module can be used for simultaneously transmitting data and audio signal, and the frequency response of the high frequency and low frequency component of the audio signal can be adjusted.
