In order to reduce the size and cost of the front-end transceiver module, a Ku-band amplitude-phase multifunctional chip is designed by using 0.13 渭 m SiGe BiCMOS technology. The single chip integrates the receiving channel and the transmitting channel. The area of the chip is 2.5 mm 脳 4.5 mm. The receiving channel of the multifunctional chip includes a front-end low-noise amplifier, a six-bit numerical control attenuator, a driving amplifier, a single-pole double-throw switch, a six-bit digital control phase shifter, and a transmitting channel with a six-bit digital controlled phase shifter. Single pole double throw switch, drive amplifier, medium power amplifier. In addition, in order to further improve the integration of the chip, the integrated power supply management unit and digital logic unit are used to realize the voltage conversion of power supply. The logic control of attenuators and phase shifters, and the switching of transceiver channels, etc. The measured results show that in the f1~f2(1GHz bandwidth, the transmission gain is 17dB, the transmission power is Psat-21.7 dBm, the receiving gain is -3dB, the receiving input power is P-1- 8.5dBmand the noise coefficient is 6.5dB5.625 擄phase-shift step. The phase shift accuracy is 4.5 擄/ 0.5 dB and the attenuation accuracy is 0.3dB / 7ASA.
