Device Overview
General Description
Available in either a connectorized or miniature surface mount package (0.240 inch x 0.150 inch), the DPX-4 is a low cost, high performance diplexer. The unique design offers high pass/low pass signal routing/multiplexing with excellent isolation. Passband insertion loss is less than 1.4 dB with rejection typically exceeding 25 dB. Besides being ideal for transmitter/receiver applications, the DPX-4 can also be used as an excellent non-reflective low pass (or high pass) filter for systems requiring broadband 50Ω impedance match (such as mixers).
Features
- Low Insertion Loss
- Superior Repeatability
- Low Profile Miniaturized, Reflow Solderable Package Option
- User defined cross over frequencies available
Applications
- Reflectionless Filter Applications
- RF Transceivers
