782422331 High frequency magnetic SMD ferrite/ceramic multilayer chip beads Inductor
Integrated crystal filter:
There are three types of crystal filters made by integrated circuit
technology: single chip, serial single chip and multiple chip.
Series monolithic crystal filters are composed of several
capacitance-coupled monolithic crystal filters. Its advantage is to
adjust the operating frequency and inhibit parasitic frequency.
The multi-chip crystal filter consists of a series of coupled
resonators, a parallel single resonator, and a capacitor. Its
characteristic is that it can form a number of attenuation peaks on
the frequency near the passband, which is beneficial to suppress
interference and improve filtering performance.
Integrated crystal filters are small in size, high in reliability
and low in cost. However, its central frequency is only 4.5 to 350
MHZ, and its relative bandwidth is 0.01% to 0.3%. Therefore, it
cannot replace the vertical crystal filter when the central
frequency is low and the passband width is wide.
