This letter presents a low power and low cost RF transceiver for Zigbee standard (IEEE 802.15.4) using a switchless front-end configuration. It is enabled by designing the matching networks that a low noise amplifier and a power amplifier can share. The transceiver has been implemented in 1P6M 0.18 μm CMOS process. The receiver achieves 4.4 dB NF, -6.5 dBm IIP3 and 25.7 dB gain with 3-step digital...
High-speed T/R converter is developed in this paper by using the combination of the circulator, the limiter and the RF switch technology. The super low noise receiving technology is realized through reducing the transmission loss and improving the gain of LNA. Experiments have proved that the T/R component's power tolerance in this paper is more than 100 W, and that the blind distance caused by it...
