Patent ID: 7616160

Claim:
An electronic device for integrating a global positioning system antenna and a digital mobile television antenna, comprising: an antenna module, comprising: a first antenna for receiving a first global positioning system signal; a low noise amplifier having a first input terminal coupled to the first antenna; a second antenna for receiving a first digital mobile television signal; a first filter module coupled to the low noise amplifier and the second antenna, for filtering the first global positioning system signal and the first digital mobile television signal to generate a second global positioning system signal and a second digital mobile television signal, for receiving a first DC voltage, and for filtering out noise from said first DC voltage to input the filtered first DC voltage to the low noise amplifier, wherein a mix signal is generated by mixing the second global positioning system signal with the second digital mobile television signal; and a receiving module comprising: a second filter module coupled to the first filter module for receiving the mix signal, for filtering both the second global positioning system signal and the second digital mobile television signal, for generating a third global positioning system signal, a third digital mobile television signal, and a fourth digital mobile television signal, for receiving a second DC voltage, and for filtering out noise from said second DC voltage to generate the first DC voltage; wherein a frequency domain of the third digital mobile television signal lies within the frequency domain of Very High Frequency (VHF), and a frequency domain of the fourth digital mobile television signal lies within the frequency domain of Ultra High Frequency (UHF).
