Multi-bank radio terminal and band switching method used therefor and program thereof
First Claim
1. A multi-band radio terminal which includes a plurality of radio units corresponding to each bands and is capable of using said plurality of frequency bands, comprising:
- a control unit which adds band switching information to frequency information that comes from a host device to designate a frequency contained in said frequency band and transmits the obtained information to said radio unit, wherein said plurality of radio units control ON/OFF according to said band switching information.

Abstract
A frequency control unit derives a frequency corresponding to each FID from frequency information sent from a host sequence and sends the frequency information to a register conversion unit, the register conversion unit converts the frequency information sent from the frequency control unit into a register value and sends the register value to a three wire serial signal generation unit, the three wire serial signal generation unit simultaneously sends out the same data with the register value as a three wire serial signal of data, clock and strobe to a radio transmitter and receiver unit, and the radio transmitter and receiver unit controls ON/OFF by its own circuit in response to the three wire serial signal and transmits and receives radio waves of a set frequency through an antenna.
