QF10.7-10000

The QF10.7-10000 is designed as crystal fiflter.

QF10.7-10000 has three applications. The first one is 4 pol filter. The next one is i.f.- filter. The last one is it would be used in mobile and stationary transceivers. That are all the main applications.

Some limiting values of QF10.7-10000 have been concluded into several points as follow. The first one is about its center frequency which would be 10.7 MHz ± 1 kHz. The next one is about its insertion loss which would be less than 4.5 dB. The next one is about its pass band at 3.0 dB which would be ± 50.00 kHz. The next one is about its ripple in pass band which would beless tham 2.0 dB at fo ± 40.00 kHz. (spurious responses up to 3 dB accepted ). The next one is about its stop band attenuation at fo ± 300 kHz which would be larger than 60 dB and it would be larger than 80dB at fo ± 500 kHz. The next one is about its alternate attenuation which would be larger than 90 dB. The next one is about its spurious response which would be larger than 50 dB. The next one is about its terminating impedance Z which would means R1 || C1 would be 50 || 0 ohm/pF and R2 || C2 would be 50 || 0 ohm/pF. The next one is about its operating temperature range which would be from -20°C to +70°C.

Also some introduction about its pin connection. The first one is about its pin 1 which would be input. The next one is about its pin 2 which would be output. The next one is about its pin 3 which would be ground-input. The next one is about its pin 4 which would be ground-output. That are all the important specifications above. And so on.
