RFM SF2027B YWWS

Unless noted otherwise, all specifications apply over the operating temperature

range with filter soldered to the specified demonstration board with impedance

matching to 50 ? and measured with 50 ? network analyzer. A dB offset exists

for RFM because of the loss introduced by using transformers on the Input and

Output.

Rejection is measured as attenuation below the minimum IL point in the pass-

band. Rejection in final user application is dependent on PCB layout and exter-

nal impedance matching design. See Application Note No. 42 for details.

"LRIP" or "L" after the part number indicates "low rate initial production" and

Either Port 1 or Port 2 may be used for either input or output in the design.

However, impedances and impedance matching may vary between Port 1 and

Port 2, so that the filter must always be installed in one direction per the circuit

design.

US and international patents may apply.
