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 push-pull amplifier for CATV,FTTX,DBS,and HDTV applications where low noise figure and low distortion are required.
The MAAM-010144 is a gallium arsenide metal-semiconductor field-effect transistor(MESFET)monolithic microwave integrated-circuit(MMIC)amplifier.The MMIC design is configured as a pair of cascode MESFET amplifiers for optimal broadband performance.Using the firm's established 0.5μm MESFET process,the device is designed for integration in a 75Ωpush-pull circuit and exhibits low distortion.
"With the introduction of the MAAM-010144,we continue to expand our portfolio of high-performance amplifiers for CATV infrastructure applications,"says product manager Graham Board.
Packaged in a TSSOP 16-lead exposed paddle package,the MAAM-010144 provides high small-signal gain of 20.5dB and+8V DC bias.The CATV amplifier operates at 50-1000MHz and exhibits a gain flatness of 0.6dB and low noise figure of 5.5dB.The device is optimized at 75Ωwith an input return loss of 18dB and an output return loss of 15dB.
