Macom Introduces 28GHz Wideband LNA

News
AQFN-packaged device is optimised to provide low noise performance across the DC to 28 GHz range

Macom Technology has announced a new packaged version of its MAAL-011141 wideband low noise amplifier (LNA) optimised to provide low noise figure performance across the DC to 28 GHz frequency range.

Now available in 5 mm industry standard AQFN packaging for pick and place assembly, the MAAL-011141 delivers wideband performance for a broad range of applications, including test and measurement, EW, ECM and radar applications.

This wideband LNA provides flat gain response across the whole band with typical gain of 17.5 dB. The input and output are fully matched to 50 Ω with typical return loss, across the band, of >15 dB. The MAAL-011141 enables ease of use by using positive gate bias, eliminating the need for a negative voltage supply. This amplifier employs an active termination circuit to achieve superior noise figure performance at the lower end of the frequency range.

"We are releasing this packaged version of the MAAL-011141 in response to the tremendous market success of the bare-die format released earlier this year. We believe that this packaged version will allow us to service customers who use standard SMT manufacturing flows," said Graham Board, senior director of product marketing, Macom. "The packaged MAAL-011141 is expected to provide customers with high performance that is comparable to the bare-die version, while simultaneously reducing the cost and complexity of the assembly process, thereby helping to accelerate time to market."
