The CMX90B701 from CML Microcircuits is a Gain Block that operates from 17 to 23 GHz. It provides a small signal gain of more than 17 dB with a noise figure of 4 dB and provides reverse isolation of more than 30 dB. This 50-ohm gain block is fabricated using a GaAs pHEMT process to provide optimum gain, linearity, and noise in a highly integrated to minimize external component count and board area. It has a turn-on time of 0.6 μs and a turn-off time of 0.9 μs. The gain block includes an active bias circuit, requires a DC supply from 3 to 5 V, and consumes 10 mA of current.
The CMX90B701 is available in a 16-lead VQFN package that measures 3.0 x 3.0 x 0.8 mm with DC-blocking capacitors. It is suitable for use in SATCOM, VSAT, Microwave backhaul, fixed wireless access, and low-current microwave amplifier applications.
