Mimix single chip MMIC up-converter (New Devices)
Houston, TX. Mimix Broadband has introduced a fully-integrated GaAs MMIC up-converter consisting of a single fundamental mixer followed by a single-stage amplifier. Using a 0.15 m gate length GaAs PHEMT technology (obtained from external sources), the XU1000 up-converter covers the 1727 GHz frequency band, and demonstrates a small signal gain of 0 dB with third order intercept point of +12 dBm across the designated band. The single chip design lowers power consumption and operates at +3.0 V DC supply. Used in conjunction with the company s XP1000 PA and XB1000 gain block amplifier, the XU1000 forms a complete millimeter-wave transmitter. It also has smaller size and lower cost designs and is suitable for millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT applications. "The integration of a gain stage with the mixer reduces the subsequent gain needed to realize the transmit power level required in a radio, reducing overall chip count in many cases," said CTO Jim Harvey. "In conjunction with the other integrated devices available for the 17 to 27 GHz bands, this device allows users to manufacture radio terminals with lower overall active device count, compared to other designs."
