An extremely compact transceiver (TRx) front-end module (FEM) has been developed for 5-GHz; wireless LAN systems. A highly integrated flip-chip TRx IC and the embedding of passive devices in a low-temperature co-fired ceramic (LTCC) with high epsilon(r) (=17) are the keys to reducing the module size to 8 x 10 x 1 mm (0.08 cc). To the best of our knowledge, this is the most compact existing FEM that demonstrates full transceiver operation and complies with the IEEE 802.11a standard.
