Abstract :
A fully-integrated 4-element phased array transmitter at 24 GHz with on-chip PAs is demonstrated in 0.18μm CMOS. It has a beam-forming resolution of 10°, a peak-to- ratio of 23 dB, and 28 dB isolation between paths. Each PA can deliver up to +14 dBm into 50 Ω in saturation. The die size is 6.8mm × 2.1mm. The transmitter bandwidth is more than 400MHz and supports up to 1Gbit/s QPSK, facilitating a gigabit wireless LAN solution.
