MACOM expands MMIC portfolio with family of 75Ω amplifiers spanning 5-1218MHz for DOCSIS3.1 CATV infrastructure

MACOM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog RF, microwave, millimeter-wave and photonic applications) has introduced five monolithic microwave integrated circuit (MMIC) amplifiers covering the downstream 45–1218MHz cable band, with two of them (MAAM-011162 and MAAM-011163) also covering the upstream 5–1218MHz band. Designed specifically for DOCSIS 3.1 infrastructure applications, the devices are a subset of MACOM's new high-performance MMIC portfolio being launched in booth #207 at European Microwave Week (EuMW 2016) at ExCel London, UK (4–6 October).

MACOM says that, as one of the few remaining pure-play RF, microwave and millimeter-wave suppliers, it designed the amplifiers to meet demanding requirements for small- to medium-signal 75Ω amplifiers in new and legacy HFC (hybrid fiber coax) networks.

The MAAM-011220 is an 18.5dB gain, high-linearity, low-noise-figure gain block operating at 45-1218MHz. It is provided in an industry-standard 3-lead SOT-89 plastic package and can be biased at either 8V or 5V (depending on available voltage rails and system requirements).

The MAAM-011194 is a differential, 3-stage, VGA (variable-gain amplifier), provided in a 5mm x 7mm PQFN package and operating at 45-1218MHz. The VGA delivers 36dB gain, 2.5dB noise figure and ACPR (adjacent channel power ratio) at output levels of +7dB above Cable Labs downstream radio frequency interference (DRFI) specifications.

The MAAM-011162 is a single-ended high-linearity, low-noise-figure amplifier covering both upstream and downstream bands of 5-1218MHz. The device is assembled in a 3-lead SOT-89 plastic package and provides 18dB of flat gain in both upstream and downstream applications.

The MAAM-011163 is a differential amplifier covering both the upstream and downstream 5-1218MHz band. Assembled in a SOIC-8EP plastic package, it has 19dB gain, what is claimed to be excellent S11 and S22 match, high linearity and 1.4dB at noise figure at 45MHz.

The MAAL-011136 is a broadband, ultralow-noise-figure amplifier operating at 45-1218MHz. It provides 20dB of flat gain and low distortion with 16dB S22, making it suitable as an input stage for low-cost fiber-to-the-x (FTTx) optical receivers and other 75Ω infrastructure applications.

Samples and reels of the MAAM-011220, MAAM-011194, MAAM-011163, MAAM-011162 and MAAL-011136 are available now.
