技術說明

本發明關於一種具三線纏繞線圈式分配器之注入鎖定射頻接收機，其包括：一個三線纏繞線圈式分配器、一注入鎖定式振盪器及一乘法器。該三線纏繞線圈式分配器具有一個一次側線圈、一個二次側線圈及一個三次側線圈。一射頻輸入訊號輸入至該一次側線圈，該二次側線圈輸出一第一差動訊號至該注入鎖定式振盪器。該三次側線圈輸出一第二差動訊號至該乘法器。利用本發明之三線纏繞線圈式分配器，可達到高靈敏度的頻率鍵移解調操作，且可降低放大器之使用數量，以減少整體注入鎖定射頻接收機之功率消耗，且降低系統複雜度。 The present invention relates to an injection-locked RF receiver having trifilar transformer splitter. The injection-locked RF receiver includes a trifilar transformer splitter, an injection-locked oscillator and a phase detector. The trifilar transformer splitter includes a primary winding, a secondary winding and a tertiary winding. RF input signal is input to the primary winding. The secondary winding outputs a first differential signal to the injection-locked oscillator. The tertiary winding outputs a second differential signal to the phase detector. Using the trifilar transformer splitter of the invention, the frequency-shift keying demodulation with high sensitivity is achieved, and the number of amplifier can be reduced so as to lower the power consumption of the injection-locked RF receiver and reduce the complexity of the system.
