M/A-COM Tech unveils GaAs broadband push-pull amplifier
Suited to CATV Infrastructure applications, the firm’s new gallium arsenide based 8.0 V, 20.5 dB gain amplifier is configured as a pair of cascade structures and claimed to have excellent broadband performance.
M/A-COM Technology Solutions (M/A-COM Tech), a supplier of high performance analogue semiconductor solutions, is marketing a new GaAs broadband push-pull CATV amplifier.
The amplifier features 20.5 dB gain, with broadband linear performance. Packaged in a 4mm QFN, 20-lead plastic package, the MAAM-009455 is an ideal inter-stage or output amplifier.
“With the introduction of the MAAM-009455, we continue to expand our portfolio of high performance amplifiers for CATV infrastructure applications,” said Graham Board, Product Manager. “The MAAM-009455 utilises M/A-COM Tech’s established 0.5 μm MESFET process to deliver a highly linear, 75 Ω, push-pull amplifier with 20.5 dB of small signal gain.”
The MAAM-009455 targets next generation CATV HFC, FTTx, HDTV, and EdgeQAM infrastructure applications, where high gain and low distortion are a requirement. The MAAM-009455 is a highly linear amplifier, with low noise figure and power dissipation. This differential amplifier uses M/A-COM Tech baluns, input and output, in order to ensure best-in-class second order performance. The amplifier also features external feedback, allowing for gain tuning.
The MAAM-009455 exhibits an excellent gain flatness of 0.5 dB typical over the 50 to 1000 MHz operating band. Input return loss has been optimized to achieve better than 20 dB across the band. Very low distortion characteristics provide excellent composite second order (CSO), and composite triple beat (CTB) performance. This amplifier exceeds DOCSIS 3.0 DRFI specifications making it an ideal output stage solution for EdgeQAM head-end infrastructure.
M/A-COM Tech says production quantities and samples of MAAM-009455 are available from stock.
