Abstract:This paper reports a high power 60 GHz push–push oscillator fabricated using 0.12 μm GaAs metamorphic high electron‐mobility transistors. By combining high‐power metamorphic high electron mobility transistor (MHEMT) optimized for millimeter‐wave operation and push–push technique, the oscillator achieved 7.4 dBm of output power at 59 GHz with 37 dBc fundamental frequency suppression. To the knowledge of the authors, this is the first monolithic push–push oscillator at V‐band fabricated using MHEMT technology. A… Show more
