Broadband CATV amplifier exhibits low distortion and high gain

October 17, 2012 // By Jean-Pierre Joosting
M/A-COM Technology Solutions has introduced today a broadband amplifier for CATV applications. The MAAM-010373 is a GaAs MMIC amplifier that exhibits low distortion and high gain in a lead-free surface mount package.

The amplifier employs a monolithic single stage design, featuring convenient 75Ω input/output impedance which minimizes the number of external components required.

The MAAM-010373 is fabricated using a pHEMT process to realize low noise and low distortion. The process features full passivation for robust performance and reliability. Operating between the 50 MHz to1100 MHz frequency range, the amplifier exhibits a high gain of 22 dB and low noise figure of 2.2 dB.

“Delivering 22 dB of gain with 20 dB output return loss, the MAAM-010373 is ideally suited for multitap drop amplifier applications” said Graham Board, Product Manager. “Customers are continuingly demanding more gain, improved linearity and reduced power dissipation. The MAAM-010373 delivers on all counts."

Other features include ±0.5 dB gain flatness, 18 dB input return loss, 20 dB output return loss, 25 dB reverse isolation, 25 dBm P1dB at 403.25 MHz, -62 dBc CSO, and -74 dB CTB.
