Abstract :
A cost-effective receiver-module with built-in patch antenna was completed as well as a transmitter. Both the transmitter and the receiver have the local-oscillator in each package and have no terminal for the mm-wave signal. The linear-gain and the noise-figure of the receiver without the antenna were 35 dB and 5.5 dB, respectively. The measured phase-noise of the receiver were ¿ 60 dBc/Hz at 1kHz, ¿78 dBc/Hz at 10kHz, and ¿88.5 dBc/Hz at 100 kHz off-carrier frequency. The average in the local-oscillation frequency variation on the temperature was 0.2 ppm/ C ° The transmission system using the transmitter and the receiver with 23 dBi horn antenna exhibited the error-free high-speed data transmission per-formance within 9 m in the indoor QPSK 100 Mbps wireless LAN.
