The CMX90G702 from CML Microcircuits is a Positive Gain-Slope Amplifier that operates from 6 to 18 GHz. It provides a small signal gain of 11.1 dB with a gain slope of +2 dB and has a P1dB of 9.3 dBm. This amplifier eliminates the need for equalization and compensates for increasing system losses with frequency. It has a noise figure of 3 dB and provides a reverse isolation of more than 16 dB. This amplifier is fabricated using a GaAs pHEMT process to provide a combination of high linearity, low noise, and low DC power consumption. It requires a DC supply from 1.8 to 5 V and consumes 22 mA of current.
This amplifier is available in a VQFN-16 package that measures 3.00 x 3.00 x 0.90 mm with RF ports matched on-chip to 50 ohms and an output DC-blocking capacitor. It is ideal for SATCOM Ku-band, fixed wireless access (FWA), 5G infrastructure & backhaul, X-band (8 – 12GHz), PA modules, and eliminating passive equalizer applications.
