Introduction

CMX90G302 is a low-power 50Ω cascadable MMIC gain module designed for various wireless applications operating in the 1.4 - 7.1GHz frequency range. The gain module features a +2dB positive gain slope across the entire band, eliminating the need for equalization while compensating for system losses that increase with frequency. The CMX90G302 is highly integrated and easy to use, reducing component count and board area. RF ports are matched to 50Ω via on-chip DC blocking capacitors. An active bias circuit enables the device to operate over a wide supply voltage range of 2.7V to 5V with a typical current of 20mA. Built on GaAs pHEMT technology, it combines low DC power consumption, low noise, and high gain. For applications requiring less gain slope compensation, the alternative model CMX90G301 is also available. The product is offered in a 3x3mm VQFN-16 package.
