Abstract :
We have developed a wide-band amplifier that can keep a gain over 10 dB at an operation current of 10 mA from 100 MHz to 3 GHz. The fabricated integrated circuit (IC) achieved a high-output third-order intercept point of 30 dBm and low noise figure of 1.6 dB at 800 MHz, respectively. The present IC employs a MODFET with 0.2-μm gate fabricated by using a phase-shift lithography technique
