Abstract :
A high performance MMIC transceiver chip-set has been developed for the 2.4 GHz to 2.5 GHz ISM band. The chip set consumes low power, making it ideal for battery powered FSK systems such as portable powered computer WLAN and portable data collection terminals. The die sizes are also very small, making them cost effective for high volume commercial applications. All transceiver functionalities, including a VCO, are integrated onto a single chip, 1.4 mm/spl times/2.79 mm die size. This chip has a very low power dissipation of 175 mW on receive and 225 mW on transmit. The second chip contains T/R and diversity switches, a 10 dB step attenuator, and the output power amplifier.<>
