Abstract
An analog processing subsystem is disclosed. Said subsystem comprising at least one antenna (202,302), a duplexer (202a,302a), at least one power amplifier (203a,203b), at least one mixer (204a,204b, 304a, 304b) and an interface connectable to a baseband processing subsystem. The at least one mixer (204a,204b,304a,304b) is adapted to down-convert and inphase/quadrature—IQ—demodulate a received analog radio frequency signal, received by the at least one antenna (202,302), to provide a received analog baseband signal and to IQ-modulate and up-convert a transmit analog baseband signal, to be transmitted by the at least one antenna (202, 302), to provide a transmit analog radio frequency signal. The analog processing subsystem is comprised on a single analog radio frequency processing chip (201,301) comprising a metallization on at least one side of the chip for integration of the at least one antenna (202,302).
