added efficiency in the field of air traffic control and weather radar.
“MPAR is an excellent example of the pioneering work M/A-COM Tech is pursuing that applies commercial manufacturing practices to high performance Government, Aerospace and Defence systems,” said Douglas Carlson, head of M/A- COM Tech’s Aerospace and Defence Business Development.
“The MPAR Panel represents a new approach to the manufacture of phased array radar having broad applicability across many future systems platforms. We and MIT Lincoln Laboratory are honoured to receive this recognition. We believe that the underlying technology represented by the MPAR Panel can enable adoption of affordable phased array systems across many communications and radar applications.”
The MPAR was developed as a next generation alternative to the existing civil radar network currently supplying air traffic and weather surveillance. The MPAR system consolidates eight separate radar systems that currently perform four unique missions --Terminal Air Surveillance, En-Route Air Surveillance, Weather Radar, and Terminal Doppler Radar.
M/A- OM Tech says that the MPAR enables increased resolution and faster operation, providing improved data for weather forecasting together with leading air traffic control capability. An MPAR system is constructed of multiple MPAR Panels functioning coherently to radiate and receive pulses of radar energy used to detect, locate and track both aircraft and weather features.
Say hello to M/A-COM’s new VGA
The firm’s latest amplifier is designed for 3G, 4G and LTE base stations.
M/A-COM Technology Solutions has introduced a new analogue control Variable Gain Amplifier (VGA) for cellular infrastructure applications.
The MAAM-009320 is designed to lower bill of August/September 2011

materials cost and complexity for OEM design engineers who are designing next generation 3G/4G/LTE base stations.
New base station designs have multi-band capabilities but numerous space constraints. 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 complimented by high gain and excellent input and output return loss.
Packaged in a RoHS compliant 4mm, 24-Lead PQFN package, the VGA is designed for operation from 400MHz – 2700MHz. External matching components are used to set the centre frequency and achieve return loss performance while analogue control is accomplished through a single control pin of 0 to +3V.
“With excellent IP3 for only 231 mA of current, the MAAM-009320 is a great choice for applications requiring gain with a wide attenuation range while maintaining linearity,” said Jack Redus, product manager. “The MAAM-009320 balances linearity and noise figure for optimal performance in cellular base station applications.”
Production quantities and samples of MAAM- 009320 are available from stock.
University engineer made Fellow of the Royal Academy
University of Manchester scientist made a Fellow of the Royal Academy of Engineering for his work on MBE and compound semiconductors.
Mohamed Missous, Professor of Semiconductor Materials and Devices at the University of Manchester, was awarded the accolade for the quality of his research and industrial experience. In total, 50 UK Fellows have been elected with six International Fellows and three Honorary Fellows.
