<p>A single chip receiver/transmitter section (202) includes an antenna switch (208), a low noise amplifier (210), a power amplifier (212) and a first (214) and second (216) mixers. The antenna switch (208) includes an antenna terminal (256) which is coupled to an off-chip band pass filter (206) which provides all of the selectivity for radio (200). Also described is a transmitter/receiver structure (300) which incorporates a transmission line filter such as band pass filter (206) formed by substrates (304 and 306) and includes the single chip transmitter/receiver section (202) imbedded inside of the structure (300).</p> |
