CMX90B701 Low Current/Noise Gain Block 17 - 23 GHz
The CMX90B701 is a low-current 50 Ω gain block suitable for a wide variety of wireless applications covering 17 - 23 GHz.
CMX90B701 is highly integrated to minimize external component count and board area. RF ports are matched on-chip to 50 Ω with an output DC-blocking capacitor. An active bias circuit helps maintain performance over a wide temperature range and supply voltage of 3 – 5 V.
The device is an easy-to-use gain block with fast enable circuit and dual-bias mode for system optimization, selecting bias of 10 mA or 15 mA.
CMX90B701 is fabricated using a GaAs pHEMT process to provide optimum gain, linearity, and noise together with low DC power consumption.
A footprint-compatible variant, CMX90B702, is available for applications covering 23 - 29.5 GHz.
Devices are available through our Distributor Network.
