CMX90B701 Low-Current, Low Noise Gain Block

The CMX90B701 from CML Micro is a low-current 50 Ω gain block suitable for a wide variety of wireless applications covering 17 GHz to 23 GHz. This gain block 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 V to 5 V. The device is an easy-to-use gain block with a fast enable circuit and dual-bias mode for system optimization, with a selecting bias of 10 mA or 15 mA. The 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 GHz to 29.5 GHz.
