Abstract:
1. A re-configurable broadband radio frequency receiver system operating on a broad frequency range and a wide input power range comprising: a broadband local oscillator with multiple frequency selection paths for generating and re-configuring at least a radio frequency signal, wherein said broadband local oscillator is configured to downconvert said radio frequency signal using at least a first quadrature demodulator to produce at least an intermediate frequency; a fixed frequency local oscillator for generating a fixed local oscillator signal, wherein said fixed frequency local oscillator is configured to downconvert said intermediate frequency using at least a second quadrature demodulator to generate at least a baseband signal; at least a microcontroller configured to provide at least an amplification path selection and digital variable attenuator settings for reconfiguring said radio frequency receiver system to desired input power; multiple power detection sections for precise detection and configuration of said desired input power of said radio frequency receiver system; a radio frequency power detection section for automatic gain control of said radio frequency receiver system; and a reference frequency section for providing at least a reference frequency to at least a frequency synthesizer, said frequency synthesizer, configured to generate at least a local oscillator frequency.
