M/A-COM Tech launches push-pull CATV amplifier with low distortion and differential inputs and outputs

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 75Ω push-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 75Ω with an input return loss of 18dB and an output return loss of 15dB.
