Abstract:
1. A radio transceiver for receiving and transmitting high frequency signals, the radio transceiver comprising: a down-conversion section configured to down-convert a received first high frequency signal, generating a down-converted signal; an up-conversion section configured to up-convert an information signal, to be transmitted, to a second high frequency signal; a variable controlled oscillator connected to the up-conversion section and to the down-conversion section for down-converting the first high frequency signal during a receive cycle and up-converting the information signal during a transmit cycle in a time division duplex mode; and a channel selection filter connected to the down-conversion section and configured to perform channel-selection filtering on the down-converted signal, thereby generating a received filtered signal; wherein the up-conversion section, the down-conversion section, the channel-selection filter, and the variable controlled oscillator are integrated on a single IC chip; and the radio transceiver is configured to employ a frequency hopping scheme.
