新概念英语培训班摘要：Some embodiments relate to a pha shifter that includes an I/Q pha shifter and at least one LC balun. Compared to conventional pha shifters, pha shifter has primarily only LC components, thereby limiting loss relative to conventional solutions.
In one embodiment, for example, a pha shifter shows a large bandwidth at 77 GHz center frequency (e.g., 1 dB amplitude error bandwidth is approximately 40 GHz; 1° pha error bandwidth is about 16.5 GHz). The inductors included in pha shifter, in contrast to the quarter wave transmission lines ud in conventional pha shifters, reduces chip area compared with conventional solutions. In some embodiments, an emitter follower helps to provide a relatively constant output that is largely independent of temperature, input power, VCC, manufacturing variation, and so on.
