MoCA® Power Amplifier/Low-Noise Amplifier (LNA)
The BCM3450 is a highly integrated, low power, MoCA® transceiver that includes the Low Noise Amplifier (LNA), Power Amplifier (PA), and T/R switch in a single chip. The BCM3450 is designed to substantially reduce the complexity of the MoCA transceiver interface, replacing numerous discrete components and a large amount of PCB area. The BCM3450 is used in conjunction with Broadcom's Integrated MoCA MAC/PHY/Tuner product line.
The BCM3450 connects to the coaxial MoCA via a triplexer and external balun to the LNA differential input. The BSC port is used to manage LNA and PA performance parameters and control the power from the MoCA MAC/PHY. The BCM3450 is optimized to interface with the BCM7420, BCM7410, BCM6829 and BCM3320. The performance of the BCM3450 meets the MoCA 1.0, 1.1 requirements for both noise figure and linearity.
- Single PA/LNA for MoCA networks with Gigabit Passive Optical Network(GPON) to MoCA bridge, home MoCA WAN networks and Broadband Home Router (BHR)
- PA capabilities include: Wideband with 30 dB gain range, Low Power 1.2W, Output Power of 2 dBm (programmable up to 5 dBm) and ACPR of 50 dBr @ 30 MHz offset
- Provides power amplification and connection to coaxial MoCA-enabled networks for Broadcom devices with integrated MoCA MAC/PHYs (BCM7420, BCM7410, BCM6816, BCM6819, BCM6829, BCM3320)
- Superior 'reach' over in-home cable environments by handling loss through multiple splitters and supporting long line runs
