MACOM debuts new ultra-low phase noise amplifier

MACOM Technology Solutions 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, 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.
