Features
• Low Ripple
• High Rejection
• Low Loss
Description
Surface mount, silver (Ag) coated ceramic
filter. Developed for use in W-CDMA repeater
and base station applications, CTS
Monoblock LR Series Filters are designed to
minimize ripple and maximize rejection.
Weight: 4.7 grams typical
Material: Filter is composed of a ceramic
block coated with Ag and a shield made of
nickel silver plated steel.
Filter complies with RoHS standards.
Note: Supplier shall test each filter to the critical electrical specifications of the above table. Any subsequent audits may deviate from in value due to measurement
repeatability among different test systems. Such deviations shall not exceed the following limits:
