 20 GHz to 36 GHz low noise amplifier targets point-to-point radio and SATCOM Jan 25, 2005 5:27 PM
Mimix Broadband Inc. has introduced a gallium-arsenide, three-stage, low-noise amplifier that covers the frequency range of 20 GHz to 36 GHz. Fabricated as a monolithic microwave integrated circuit (MMIC) and identified as the XL1002, this low-noise amplifier exhibits a small signal gain of 23 dB and a noise figure of 2.5 dB across its operating frequency range. The amplifier is well suited for wireless communications applications—such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), and SATCOM. For applications requiring lower gain, a two-stage companion part, the XL1001, is available. The device has simple power supply requirements, requiring only a single supply voltage source—there is no need for a plus, minus power source. Due to its balanced design, the XL1002 offers an excellent input and output match. Mimix performs 100% on-wafer RF, DC and noise figure testing on the XL1002, as well as 100% visual inspection to MIL-STD-883, method 2010. The chip surface is passivated to protect the device and to provide it with backside via holes and gold metallization, enabling either conductive-epoxy or eutectic-solder, die-attach. Engineering samples and production quantities are available from stock.
