1 VWA AA Double TIA GHz/ GHz ZT>350 Ohms Features Description The VWA AA is a double transimpedance amplifier designed on a 0.15 µm phemt process. The two embedded devices are capable of more than +10dBm of output power at saturation regime. And more than +8dBm of output power at 1 db of gain compression regime. It provides 16dB of linear gain for each sub-band. When operating with VD=+ 2.5V, with a small consumption of 25mA. The design has been optimized to provide high signal to noise ratio. Applications Radar / ECM / ECCM Test and measurement Broadband / datalink communication Mounting circuit proposal Tools Transimpedance amplifier phemt GaAs MMIC SUB-BAND 1: SBA from 2.9GHz to 3.4GHz.
