摘要
A dual-band receiver employs the Weaver architecture with two tuned radio-frequency stages and a common intermediate-frequency stage to allow operation with 900-MHz and 1.8-GHz standards while using only two oscillators. Fabricated in a digital 0.6-mu m CMOS technology, the receiver achieves an overall noise figure of 4.7 dB and input third intercept point of -8 dBm at 900 MHz, and 4.9 dB and -6 dBm at 1.8 GHz, The voltage gain is 23 dB with a power dissipation of 75 mW from a 3-V supply.
