無線受信装置
Document Type and Number:
Japanese Patent JP5002058
Kind Code:
B2
Abstract:
Provided is a radio receiving device which can simultaneously receive signals of different communication systems without increasing the circuit scale and the size of the entire device and enables a reduction in manufacturing cost. In this device, a radio unit (150) performs radio processing of television broadcast signals received from plural antenna (101) and antenna (102). A radio unit (154) performs radio processing of a GPS signal received from a GPS satellite. An IF unit (151) limits and amplifies the band of the radio-processed television broadcast signal from the antenna (101). A switch (125) selects either the radio-processed television broadcast signal from the antenna (102) or the GPS signal radio-processed by the radio unit (154). An IF unit (155) limits and amplifies the band of the television broadcast signal or the GPS signal selected by the switch (125) and a switch (126).
