摘要： Multi-channel communication devices and methods are provided, which employ a filter bank, connected between antenna(s) and wideband converter(s), that comprises many narrowband surface acoustic wave (SAW) filters having respective distinct frequency bands within a bandwidth of the wideband converter(s). For example, devices may be configured as multi-channel receivers with SAW filters replacing current heterodyne circuitry and achieving effective separation of reception channel and effective attenuation of adjacent blocking signals in a compact device. In other examples, devices may be configured as multi-channel transmitters and/or transceivers, possibly having a variable number of channels, to realize compact multi-channel radio.
