CML MICROCIRCUITS CMX90G301 and CMX90G302 Positive Gain Slope Amplifiers are developed using firm’s SµRF RFIC/MMIC design capability. The general-purpose gain blocks are suitable to a wide range of wireless applications operating in the 1.4 – 7.1GHz frequency range, including 4G/5G infrastructure applications and devices operating in licence-free bands. Both devices use GaAs pHEMT technology to achieve an optimal combination of low dc power, low noise, and high gain. CMX90G301 has +1dB positive gain slope, while the CMX90G302 provides a +2dB gain slope for applications requiring more gain-slope compensation. Both devices deliver a small signal gain of 14.8 – 16.0dB, a P1dB output rating of +11.5dBm at 3.5 GHz and a low noise figure of 2dB.
