VWA5000054AA

Abstract – The VWA 5000054 AA is a distributed amplifier designed on a 0.15μm pHEMT process. The device includes an internal biasing circuit which can be used to feed directly the drain current, as an alternative to bias the drain from the HF-Output access. Depending on the desired low cut off frequency, external components can be added to ensure operations started from 30KHz to 2GHz through up to 40GHz. The device includes also an embedded output signal detector and an embedded input gate biasing circuit which can be used to reduce the power consumption in many linear receiving amplifier chains. It is capable of more than +21dBm of output power at saturation regime, up to 40GHz. And more than +17dBm of output power at 1 dB of gain compression, up to 34GHz. It provides more than 12dB of linear gain from DC to 44GHz with a positive slope of +0.0375dB/GHz, up to 40GHz. This device can provide up to 10dB gain up to 50GHz with an excellent group delay. Optimized biasing configurations are proposed depending on the input power level pattern.
