Buffer amp runs from 18 to 38GHz
A new gallium arsenide MMIC three stage buffer amplifier features ultrawide bandwidth and high dynamic range.
MMIC mixer is optimised as downconvertor
A new gallium arsenide monolithic microwave integrated circuit fundamental balanced mixer is optimised for use as a downconvertor.
The image reject mixer eliminates the need for an image bandpass filter after the amplifier to remove thermal noise at the image frequency.
Using 0.15um gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, these devices cover the 17 to 25GHz frequency bands.
The receiver has a noise figure of 2.5dB and 20dB image rejection across the band.
The transmitter has a +23dBm output third order intercept point (OIP3) and 15dB image rejection across the band.
This receiver and transmitter pair, identified as XR1006-QD and XU1002-QD, respectively, are well suited for wireless communications applications such as millimetre-wave point-to-point radio, local multipoint distribution services (LMDS), satcom and Vsat applications.
"This receiver and transmitter pair is ideally suited for 17.7-19.7GHz PDH microwave radio applications, with image rejection, +2dBm LO drive level and low noise figure in the receiver".
"The high level of integration, along with true surface mount packaging allow customers to lower their material and assembly costs and improve their time to market", stated Paul Beasly, Product Manager, Mimix Broadband.
Mimix performs 100% on-wafer RF and DC testing on these products.
The devices come in a 7 x 7mm QFN surface mount package, offering excellent RF and thermal properties, and the packages are RoHS compliant.
Engineering samples and small production quantities are available today from stock production.
