Abstract :
This paper presents a fully integrated receiver front-end for time-division multiplexing phased-array system. The 30 GHz front-end includes a low-noise amplifier (LNA), a 4:1 multiplexer, a mixer, and a clock sequencer. The circuit has been implemented in a 0.25 ¿m, 130 GHz-fT SiGe process. The front-end shows a input reflection coefficient (S11) of -20 dB, a minimum measured LNA-Multiplexer noise figure (NF) of 4.1 dB, and a maximum conversion gain (CG) of 18.9 dB at 30 GHz. Measurements show a 1dB input compression point of -32.3 dBm, a third order intercept point (IIP3) of -22 dBm, and a channel isolation of 23 dB at 30 GHz. This system reduces receiver power consumption by reducing ADC numbers.
