Abstract:
1. An integrated antenna device disposed near a plurality of antennas of mutually different signal systems, the integrated antenna device comprising: a plurality of tuner units each having a frequency converter configured to convert a high frequency signal received at a corresponding one of the antennas into an intermediate frequency signal; an AD converter configured to convert output signals of the tuner units into digital signals; a multiplexing processor configured to multiplex the received digital signals AD-converted at the AD converter; a serial communicator configured to output, to an outside, a received multiplex digital signal multiplexed at the multiplexing processor and to receive a control signal from the outside; a power-feeding switch for individually controlling power feeding of the tuner units on the basis of the control signal received at the serial communicator; and a pseudo-signal generator configured to generate a pseudo-signal that simulates an output signal of the AD converter, wherein the multiplexing processor uses the pseudo-signal generated at the pseudo-signal generator instead of a received digital signal corresponding to a tuner unit that is stopped from being fed power by the power-feeding switch.
