摘要

介绍了一种用于雷达s波段的小型单片6位数字移相器(DPS)的设计和测试结果。根据插入损耗、幅度和相位误差以及密实度选择每个比特的最佳设计拓扑。移相器采用美国UMS铸造厂的$0.25 \mu \ mathm {m}$ p-HEMT GaAs工艺制备。所开发的DPS在$4.8 \ mathm {~mm} \ × 2.6 \ mathm {~mm} \ × 0.1 \ mathm {~mm}$的功耗范围内实现，具有$6.0 \ mathm {~dB}$的插入损耗，其显著特点是电压波驻比小于1.57,RMS幅值误差小于$0.30 \ mathm {~dB}$， RMS相位误差小于1°。

S band Six-bit Digital Phase Shifter for RADAR applications

This paper presents design and test results of compact monolithic 6-bit digital phase shifter (DPS) at S-band for radar applications. The optimum design topology of each bit is selected based on insertion loss, amplitude and phase errors and compactness. The phase shifter is fabricated using $0.25 \mu \mathrm{m}$ p-HEMT GaAs process from UMS foundry. The developed DPS is realized within the footprint of $4.8 \mathrm{~mm} \times 2.6 \mathrm{~mm} \times 0.1 \mathrm{~mm}$, exhibits $6.0 \mathrm{~dB}$ insertion loss with salient features of voltage wave standing ratio of less than 1.57, RMS amplitude error less than $0.30 \mathrm{~dB}$ and RMS phase error better than 1° at 3.2GHz with 100 MHz bandwidth.
