Dielectric Filters (DF-B)
DeMint Dielectric Filter (DF-B) has a Ripple in Band Width (dB) 0.5 max. DeMint (DF-B) filter manufactures with a fine-grained, high density, high purity dielectric material to keep the best performance with a ripple in band width (dB) 0.5 max.
The (DF-B) filter's small size (8.5 x 6.0 x 3.0 mm) means they require more less mounting space. Available Center Frequency 650 MHz to 916 MHz with V.S.W.R 1.5 max., insertion loss 2.0 ~ 5.0 (dB) max.
RF dielectric filters are mounted in a surface mount package which assures mechanical stability and excellent lead coplanarity. RF filters can be customed designs and tighter tolerances available on request.
Products conform to the RoHS directive. Application of specific designs also available including different Dielectric values and Q specifications adjusted to frequency requirements.
