Abstract :
The development of 60 GHz-band ultra-miniature FM/frequency-shift keying (FM/FSK) transmitter/receiver modules fabricated with a complete monolithic-microwave integrated circuits (MMIC) chip set, including dielectrically stabilized fundamental-frequency oscillators for multimedia wireless communication systems, is reported. The 0.9 cc transmitter module, which consists of a voltage controlled oscillator (VCO) and two power amplifiers, exhibits 11.5 MHz/V modulation sensitivity, 10.2 dBm output power, and -2.4 ppm/°C frequency stability. With the receiver module, which consists of low noise amplifier (LNA), a mixer, and a local oscillator (LO), 5.4 dB double-side band (DSB) noise figure with 10.8 dB downconversion gain has been achieved. The 60 GHz band monolithic dielectric-resonator (DR) stabilized oscillators offer a practical approach to ultra miniature transmitter/receiver modules for high-speed wireless LAN systems with data rates greater than 10 Mbps and for video-signal and compressed HDTV-signal (MUSE) transmission systems
