CMX90B702 RF Amplifier by CML Microcircuits

The CMX90B702 from CML Microcircuits is a Gain Block that operates from 23 to 29.5 GHz. It provides a small signal gain of 17.5 dB with a noise figure of 4 dB and has an output P1dB of 5 dBm. This gain block has been fabricated using a GaAs pHEMT process to provide optimum gain, linearity, noise, and low DC power consumption. It is highly integrated to minimize the external component count and board area. The gain block requires a single positive DC supply from 3 V to 5 V and consumes 40 mW of power. It also includes an active bias circuit that helps maintain performance over a wide operating temperature and supply voltage range.

The CMX90B702 includes on-chip matched ports (50 ohms) with an output DC-blocking capacitor. It is available in a surface-mount package that measures 3 x 3 mm and is ideal for 24 GHz ISM band, fixed wireless access (FWA), Satcom (K and Ka-band), 5G mmWave infrastructure, and microwave backhaul applications.
