Introduction

This device is a low-power, 50Ω cascadable MMIC gain block designed for a wide range of wireless applications operating in the 1.4 – 7.1 GHz frequency range. The gain block features a +1dB positive gain slope across the band, compensating for frequency-dependent system losses without requiring equalization. The device is highly integrated and easy to use, minimizing component count and board area. The RF ports are internally matched to 50Ω with integrated DC-blocking capacitors. An active bias circuit enables operation over a wide supply voltage range of 2.7V to 5V at a typical current of 22 mA. The GaAs pHEMT process delivers a combination of low DC power consumption, low noise, and high gain. For applications requiring greater gain slope compensation, the alternative model CMX90G302 is available. Supplied in a 3×3mm VQFN-16 package.
