Boosting communications signals across wide bandwidths usually suggests a number of amplifiers to cover multiple bands. But a single compact amplifier in die form from MACOM Technology Solutions, the model MAAM-011109-DIE, covers the full bandwidth of DC to 50 GHz and provides a number of flexible controls that enable this low-noise amplifier (LNA) to tailor performance as needed across that wide frequency bandwidth.
Model MAAM-011109-DIE (see figure) is fully matched to 50 Ω and exhibits better than 15-dB return loss and more than 15-dB gain across the full frequency range. The typical noise figure is 3.5 dB. The amplifier delivers +21 dBm output power at 1-dB compression. It has a third-order intercept point of +29 dBm.
The RoHS compliant component has gold-plated contact pads and backside and is 100% on-wafer DC and RF tested. It measures 1.97 × 1.30 × 0.1 mm and draws190 mA from a +5-VDC supply. It includes a gate-bias adjustment control that provides 15-dB gain control (from 0 to -1 VDC) and includes a temperature-compensated power detector that provides a DC voltage relative to the output power for consistent performance over changing environmental conditions.
“The DC-50 GHz operation, adjustable bias control for power and gain, and low noise performance make the device a highly versatile solution for multiple wideband applications,” says Paul Beasly, MACOM product manager .The amplifier is well suited for diverse broadband applications, including in electronic-warfare (EW) systems and in test-and-measurement equipment.
