MACOM debuts new ultra low phase noise amplifier

MACOM Technology Solutions has announced the first entries in its new portfolio of wideband, ultra low phase noise amplifiers.

Available in 2.8 x 1.73 x 0.1 mm bare-die and 5x5mm, 32-lead AQFN packaged formats, the new MAAL-011151 is ideally suited for use as a low phase noise amplifier stage for signal generation applications spanning a host of system designs targeting test and measurement (T&M), EW, ECM, and radar.

Phase noise is a critical specification in defining the frequency stability of a signal source, with significant implications for receiver sensitivity performance. MACOM’s MAAL-011151 minimizes phase noise contribution in providing LO signal gain, enhancing spectral integrity for T&M and communications systems, target acquisition for radar, and aerospace and defense (A&D) applications.

The MAAL-011151 will provide 16 dB of linear gain across the 2 to 18 GHz frequency band, 17.5 dBm of P1dB and 5 dB of noise figure at 10 GHz with input and outputs that are fully matched to 50 Ω and are DC blocked. Amplifier control is available through the use of a control circuit or by direct bias injection. The MAAL-011151 is fabricated using a low phase noise HBT process which features full passivation for enhanced reliability.

“With the introduction of MACOM’s new MAAL-011151 ultra low phase noise amplifiers, we’re investing in a growing portfolio of signal generation components that encompasses high-performance comb generators, mixers, and more,” said Graham Board, Senior Director of Product Marketing, MACOM. “As we expand this portfolio to include additional discrete amplifiers covering additional frequencies, and integrated low phase noise LO modules, system designers will benefit from seamless device compatibility and exceptional performance across the signal chain, with decades of MACOM application expertise to help them achieve their aggressive design goals.”
