M/A-COM Tech launches 400–2700MHz analog control VGA for cellular infrastructure

M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components, and subassemblies for RF, microwave and millimeter-wave applications) has launched a new analog control variable gain amplifier (VGA) for cellular infrastructure applications. The MAAM-009320 is designed to lower bill of materials cost and complexity for OEM design engineers that are designing next-generation 3G/4G/LTE base-stations.

New base-station designs have multi-band capabilities but numerous space constraints, says M/A-COM Tech. The MAAM-009320 delivers higher levels of integration and space savings by performing three circuit functions in a single 4mm PQFN package. The MAAM-009320 has a wide frequency range complemented by high gain (25.5dB) and what is claimed to be excellent input and output return loss. Noise figure is 3.0dB, attenuation range is 26.5dB, OIP3 is 42.0dBm.

Packaged in a RoHS-compliant 4mm, 24-lead PQFN package, the VGA is designed for operation from 400–2700MHz. External matching components are used to set the center frequency and achieve return loss performance while analog control is accomplished through a single control pin of 0 to +3V.

“With excellent IP3 for only 231mA of current, the MAAM-009320 is a great choice for applications requiring gain with a wide attenuation range while maintaining linearity,” says product manager Jack Redus. “The MAAM-009320 balances linearity and noise figure for optimal performance in cellular base-station applications.”
