[0019] Example: Ku-band LTCC transceiver components
[0020] figure 1It is the overall block diagram of high-performance and low-cost miniaturized LTCC transceiver components. The transceiver component consists of two parts. The left side of the dotted line is the radio frequency part of the transceiver component, and the right side of the dotted line is the intermediate frequency part of the receiving branch. It contains 13 functional circuit modules in total. The transmission direction of the sending and receiving signals is: the transmitting signal enters the transmitting branch from switch 2 (SW2), passes through the phase shifter (PS), attenuator (ATT) and switch 3 (SW3) and reaches the power amplifier (PA), and the signal is amplified to After a certain power, it enters the circulator (CL) and outputs to the antenna interface; the echo signal comes in from the antenna, passes through the circulator (CL) and enters the receiving branch, and the signal goes along the low ...
