Abstract

An 8692 GHz frequency shift keying (FSK) transmitter with an integrated antenna in 0.5 μm enhancement/depletion-pseudomorphic high-electron mobility transistor (E/D-PHEMT) technology is presented in this letter for broadband millimeter-wave applications. The transmitter consists of a push-push voltage controlled oscillator (VCO) and a slot antenna. The chip size of the transmitter is 2× 1 mm2. The transmitter demonstrates a RF output power of higher than 8 dBm over the operation frequency and an antenna gain of 3 dBi with broadside radiation pattern. The transmitter is also successfully evaluated with high speed FSK digital modulations. The dc power consumption of the transmitter is within 54 mW with a dc supply voltage of 2 V.
