Gain Block offers Positive Slope
Posted On 26 Jan 2022
RFMW announces design and sales support for a positive slope gain block from CML Microcircuits. The CMX90G301 is a low-power, 50 Ω cascadable MMIC gain block for 1.4 to 7.1 GHz applications. +1 dB of positive gain-slope across the band eliminates the need for equalization and compensates for increasing system losses with frequency. Highly integrated, the CMX90G301 minimizes component count and board area. RF ports are matched to 50 Ω with DC-blocking capacitors. An active bias circuit allows the device to operate over a wide supply voltage of 2.7 to 5V with typical current of 20 mA. GaAs pHEMT fabrication provides a combination of low DC power, low noise and high gain.
