Zusammenfassung:This paper presents an F-band direct digital ASK modulation transmitter. A high speed bias current modulator and a large bandwidth power amplifier are key building blocks in this system. The digital PRBS signal is generated by an on chip high speed 9-bit LFSR. A transmitted data rate of 5Gb/s is achieved and the measured peak output power is 6dBm at 110GHz. The peak LO to RF gain is 16dB. Total chip area is 0.5mm 2 , the active RF area occupies 0.1mm 2 and the digital baseband measures 0.01mm 2 .
