MACOM Technology Solutions has introduced seven new high-performance CATV amplifiers designed for 5V operation covering both upstream 5-300 MHz and downstream 45-1218 MHz. These amplifiers are offered in a single ended SOT-89 package and differential SOIC-8EP package. Additionally each product family is layout compatible allowing design engineers performance flexibility on the same system board.

These devices, designed specifically for DOCSIS 3.1 Distributed and Legacy HFC (hybrid fiber coax) Networks, are scheduled for launch during this year’s EDI CON 2017 show in Shanghai.

The DOCSIS3.1 standard is addressing the market demand for higher broadband performance from MSOs (Multiple Service Operators). As a leading supplier of active and passive products to broadband OEMs (Original Equipment Manufacturers), MACOM’s latest active families offer design engineers the ability to select needed performance while optimising power consumption.

“MACOM’s latest Wired Broadband single ended and differential amplifier families offer optimal balance between linearity, noise figure and power efficiency, which are required in today’s infrastructure networks,” said Graham Board, Senior Director, Multi-Market Products, at MACOM. “We are excited to add these new leading edge amplifiers to our extensive portfolio of active and passive CATV products.”

Single Ended 5V SOT-89 Family

The MAAL-011139 is a 21.5 dB Gain, low noise figure, high linearity amplifier operating from 5-1218 MHz. This versatile amplifier is assembled in a 3lead SOT-89 plastic package and can be biased from 3 to 5 volts with adjustable current achieving a noise figure of 1.2dB and OIP3 of 34 dBm.

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

The MAAM-011251 is a single-ended high linearity, low noise figure amplifier covering both up and downstream bands of 5-1218MHz. This device is assembled in a 3lead SOT-89 plastic package and provides 15 dB of flat gain in both up and down stream applications.

The MAAM-011258 is a single-ended high linearity, low noise figure amplifier covering both up and downstream bands of 5-1218MHz. This device is assembled in a 3lead SOT-89 plastic package and provides 12 dB of flat gain in both up and down stream applications.

Differential 5V Family SOIC-8EP Family

The MAAM-011163 is a 19dB Gain differential amplifier covering both upstream and downstream band 5-1218 MHz. Assembled in a SOIC-8EP plastic package, this device offers noise figure of 2.4 dB and OIP3 of 42 dBm.

The MAAM-011240 is a 17dB Gain differential amplifier covering both upstream and downstream bands 5-1218 MHz. Assembled in a SOIC8EP plastic package, this device offers noise figure of 2.6 dB and OPI3 of 44 dBm.

The MAAM-011250 is a 15dB Gain differential amplifier covering both upstream and downstream bands 5-1218 MHz. Assembled in a SOIC8EP plastic package, this device offers noise figure of 2.8 dB and OPI3 of 44 dBm.
