| Abstract: |
| This paper is a technique report about the developing QPSK demodulator (i.e.loose tail loop). This is a new type demodulator, circuit is novel, making is easy and performance is good. specially, this PLL is suitable to application in satellite communication equipments with higher carrier frequency and microwave communication equipments. At the present, this PLL has been applied in satellite communication equipments in foreign countries. In the paper loose tail loop was described in detail from theoretical analysis to practical circuit making. |
