These filters are measured based on their 3db bandwidth and is best explained by example.
10 7 mhz fm ceramic filter.
The filters have different names depending on the structures and the materials used.
13 5mm is for ammo packaging left blank if standard abracon is iso9001 2015 certified 5101 hidden creek lane spicewood tx 78669.
The ceramic filter that is used in this circuit are cheap and available in a variety of insertion losses and banwidths.
The system is then built with cc1000 a 10 7 mhz ceramic filter and an external 10 7 mhz demodulator.
The types the principles and the features of the filters which are currently used are shown in table 1.

This circuit is used in many application such as cell phone base station receivers final if and fm broadcast receivers.
Looking at the figure it shows the traces of the bandpass characteristics of four commonly used fm ceramic filters 280 230 180 and 150 khz.
5mm is for bulk parts.
The development of consumer radio from the late 1950 s to the present about 1975 10 7 mhz ceramic filters for fm if began to show up in table model radios and soon became common.
This is 10 7 mhz if amplifier circuit.
In most cases it does not have infinitely steep slopes at the edge of the pass band and the ultimate rejection in the stop bands is not infinite.

The action of a tuner mixer stage translates all fm stations down to a frequency of 10 7 mhz.
Murata ceramic filters 10 7 mhz 10 7 mhz signal conditioning are available at mouser electronics.
Ceramic filters can also be employed for other purposes such as am and tv if stages but this page concentrates on their use in fm tuners and receivers.
Ceramic if filters are centered at 10 7 mhz for fm radios because the if intermediate frequency is 10 7 mhz.
A 280 khz filter means that you will have 3 db loss at 280 khz from the center frequency.
