M/A-COM Tech launches MMIC doubler with integrated gain,self-biased doubler and driver stages
M/A-COM Technology Solutions Inc of Lowell,MA,USA(which makes analog semiconductors,components and subassemblies for RF,microwave and millimeter-wave applications)has launched a gallium arsenide monolithic microwave integrated circuit(MMIC)doubler for VSAT applications.
The XX1010-QT is an active doubler in a RoHS-compliant 3mm x 3mm 16-lead plastic QFN package that delivers+20dBm output saturated power(Pout)and 35dBc fundamental suppression.Using a GaAs pseudomorphic high-electron-mobility transistor(pHEMT)process,the XX1010-QT covers the 14.625-15.0/29.25-30.0GHz frequency bands and integrates a gain stage,doubler and driver amplifier into a single device.
The doubler is suited to SatCom and millimeter-wave point-to-point radio applications,says the firm.The XX1010-QT integrates DC blocking and bypassing capacitors,eliminating the need for any external components.The device has a self-bias configuration,requiring only a positive 5V supply.The supply currency is 200mA.?Input return loss is 12dB and output return loss is 14dB.
"The high level of integration coupled with a standard 3mm x 3mm plastic QFN package offers our customers an optimal cost-effective solution by saving precious board area and reducing component count,"claims product manager Amer Droubi."The XX1010-QT is an ideal driver stage to the final output power amplifier in Ka-band VSAT terminals."
