Buffer amp runs from 18 to 38GHz
A new gallium arsenide MMIC three stage buffer amplifier features ultrawide bandwidth and high dynamic range.
Mimix Broadband has developed a gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) three stage buffer amplifier with ultrawide bandwidth and high dynamic range Using 0.15 micron gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, this buffer amplifier covers the 18 to 38GHz frequency bands and can operate at 3.5 or 5.5V

High-power amplifier takes bias circuit onboard
A new GaAs MMIC two-stage single-ended X-band high-power amplifier integrates an on-chip gate bias circuit to simplify biasing.
This device can also be operated with all three stages biased in parallel or with independent bias for input and output stages, as required to optimise performance.
This MMIC device has a small signal gain of 21dB with a noise figure of 3.2dB across the band.
It also has 11dBm OP1dB at low noise bias or can provide 15dBm OP1dB at power bias.
This amplifier, identified as XB1006, is an excellent LO driver or buffer amplifier, and is well suited for wireless communications applications such as millimetre-wave point-to-point radio, local multipoint distribution services (LMDS) and satcom.
"The design of this device allows it to be used in many different functional modes in a radio, simplifying design and manufacturing issues, including inventory", stated Dr Jim Harvey, CTO of Mimix Broadband.
"At low noise bias it is suitable as an LNA, and in power bias it can support LO buffer and transmit buffer roles".
Mimix performs 100% on-wafer RF, DC and noise figure testing on the XB1006, as well as 100% visual inspection to MIL-STD-883 method 2010.
The chip also has surface passivation to protect and provide a rugged part with backside via holes and gold metallisation to allow either a conductive epoxy or eutectic solder die attach process.
Engineering samples are available today from stock, and production quantities are available 6-8 weeks ARO.
Technical support is also available from Mimix's applications engineers.
