Yes. There are now customer integrated circuits that are whole radio
transceivers....all in one chip with very few external parts, mostly
filters so it only hears one channel at a time. It's how they cram a
sellphone, Bluetooth, 700 Mhz digital TV receiver, GPS all into a tiny flat
PDA with a 3" screen....integration.
