Hello. I intend to use LT5517 quadrature demodulator in my design. From its datasheet, there are bandpass filters right before the differential RF Input Pins. I need a bandpass filter with a center frequency of 450MHz, and bandwidth of 100kHz.I have been doing research on the possible bandpass filter chips I can use here, but it has been in vain. Are there any suggestions for this?
For the LO inputs, I shall use ADF4351 Wideband Synthesizer to provide the necessary frequencies.
