Mimix Broadband announced the introduction of a totally integrated gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) up-converter on a single chip. This device is a single fundamental mixer followed by a single stage amplifier. Using 0.15 micron gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, the up-converter covers the 17 to 27 GHz frequency band. Furthermore, this up-converter has a typical small signal gain of 0 dB with a typical third order intercept point of +12 dBm across the band. This single chip device features low DC power consumption and operates at +3.0 V DC.
This up-converter, identified as XU1000, used in conjunction with Mimix's XP1000 power amplifier and XB1000 gain block amplifier forms a complete millimeter-wave transmitter. Furthermore, the XU1000 enables the development of smaller size and lower cost designs and is well suited for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT applications.
