In this report, we present a 300-GHz ASK receiver MMIC for future terahertz communications. Thanks to the short wavelength of the terahertz waves, all necessary components such as a dipole antenna, high gain RF amplifier, envelop detector and output differential data amplifier have been fully integrated in single ICs with an area of 1000×2500μm2 The receiver MMIC was assembled with a silicon lens which improved antenna directivity and gain. The packaged receiver module with the silicon lens is expected to provide approximately 24-dBi beam directivity. Measured RF and baseband bandwidths of the receiver module are around 30 and 15 GHz, respectively, when a single bias of 3.3 V and total current of around 86 mA are applied. With the receiver module, simple wireless data transmission was conducted for up to 24 Gbps in the 300-GHz band. At 1 2.5 Gbps, error-free data transmission (bit error rate <109)over 0.3 m was achieved with the trans-mission power of 16〜dBm and a 25-dBi transmitting antenna. With 10-dBm transmission power, measured Q-factors of the received eye patterns were larger than 6 for up to 20 Gbps, which implies that the bit error rate will be less than 10-9
