IF FILTER BANK FB1004 is an IF filter bank suitable in front of high speed ADCs in receiver chains
DESCRIPTIONFB1004 is an IF filter bank suitable in front of high speed ADCs in receiver chains.
The filter channels are centered around 240MHz and selected by TTL inputs.
The unit incorporates highly selective SAW filters with bandwidths of 0.3MHz, 5MHz, 10MHz and 20MHz. The filter bank also includes a selectable bypass RF through path.
On SAW filter channels, adequate gain blocks were included to compensate the SAW filter losses. The overall gain is 0dB ± 1dB for those channels.
