Design and performance of an X-band successive detection log amplifier/limiter MMIC covering 8 to 12 GHz is reported. The three-stage amplifier is a cascadeable block providing 20 dB nominal gain, 5.5 dB noise figure, +7 dBm limited output, < 2:1 input/output VSWR, and a 20 dB log range at 50 mV/dB. This is the first reported use of successive detection at X-band frequencies. Previously reported results have been below 7 GHz, required four times the power for the same dynamic range, and twice the chip count. The amplifier is implemented in a fully selective 0.15 /spl mu/m double recess power PHEMT process.
