DC to 45GHz / 12dB Gain / 20dBm PSAT
Wideband Distributed Amplifier
Internal Active Bias-Tee

The VWA5000079AA is a wideband distri- buted amplifier designed on a 0.15μm pHEMT process.
The device is capable of more than +20dBm of output power at saturation regime, up to 45GHz and more than +16dBm of output power at 1dB of gain compression, up to 40GHz. It pro- vides more than 9dB of linear gain from DC to 45GHz with a positive slope enabling 14dB gain at 45GHz when operating with VD= +9V, with an excellent group delay. The design integrates an internal active drain biasing system that allows to avoid external Bias-Tee structure to feed the drain current. The supply current is as low as 200mA when operating with VD = +9V.
