2, single-sideband circuit production is a very critical part of the crystal filter, different manufacturers of different batches of Crystal parameters vary greatly, simply according to the theoretical calculation of the production of the filter is basically not very useful, which This is also an important reason for the failure of many players to produce the circuit.
3,If there is a scalar or vector network with high resolution, the crystal filter is basically made under the theoretical Guided by the theory, it is easier to succeed, but it also requires a lot of experiments and multiple corrections of the parameters, which is also However, the effect of the crystal filter made with the assistance of the instrument is still guaranteed.
Color: As Shown
Material: PC+metal
The parameters of this 9M state z crystal filter are as follows:
a,The center frequency is about 8.998MHz;
b,-6dB bandwidth is about 2.3kHz;
c,The center frequency loss is about -4.73dB;
d,The rejection ratio is close to 100dBc:
e,The filter has used LC impedance matching circuit to make the impedance of both ends become 50 ohms, without LC circuit, the impedance of both ends is about 120 ohms. The impedance at both ends without LC circuit is about 120 ohms.
