Abstract
A multiband receiving apparatus and multiband transmitting apparatus using a tunable band is provided. The receiving apparatus includes a receiving unit for receiving radio frequency (RF) signals, and a tunable filter unit for selectively outputting the received RF signals. As a result, a complicated RF transceiving system is simplified, and time and cost for developing and designing a transceiving apparatus are reduced.
Claims8
A multiband receiving apparatus, comprising:
- a receiving unit for receiving radio frequency (RF) signals from a plurality of frequency bands, wherein each of the frequency band comprises a plurality of frequency channels;
- and
- a tunable filter unit for filtering the RF signals received through the receiving unit according to the channel, and selecting and outputting an RF signal filtered at a predetermined channel.
A multiband transmitting apparatus, comprising:
- a tunable filter unit for filtering radio frequency (RF) signals of a plurality of frequency bands according to the channel, and selecting and outputting an RF signal filtered at a predetermined channel, wherein the frequency bands each comprise a plurality of frequency channels;
- and
- a transmitting unit for transmitting the signal output from the tunable filter unit.
