60GHz ultra compact transmitter/receiver with a low phase noise PLL-oscillator

In this paper, we present a transmitter and a receiver for a millimeter-wave video transmission system. The size of each is 110 mm/spl times/55 mm/spl times/23 mm, as a result of using an antenna-integrated millimeter-wave module and a filter-integrated SHP (sub-harmonically pumped) mixer MMIC. Both transmitter and receiver have a local signal of 29.5 GHz, for up/down-conversion, which is generated by multiplying a signal from a 1.8 GHz PLL-oscillator. A low phase noise of -103 dBc/Hz at 100 kHz offset was achieved.
