Date of Grant	2015/02/15
Patent Title	Radio apparatus
Details	A radio apparatus includes an antenna; an amplifier that amplifies a radio signal, received via the antenna; a first mixer that frequency converts the amplified radio signal to generate a first analog signal; a first A/D converter that converts the first analog signal to generate a first digital signal; a second mixer that frequency converts the amplified signal to generate a second analog signal; a second A/D converter means that converts the second analog signal to generate a second digital signal; a demodulator means that demodulates the first and second digital signals to generate a demodulated signal; a detector that detects a preamble from the first digital signal; and a control means that halts the second mixer and second A/D converter during the wait for the radio signal and that activates the second mixer and second A/D converter when the detector detects the preamble.
