Diplexers & Duplexers Products and Services

  1. Tunable Filters And Bandpass/Bandstop Diplexers
    K&L Microwave’s tunable filters and bandpass/bandstop diplexers are typically used in test and measurement applications. The diplexers feature broadband matching at the common port, low insertion loss, and high isolation. What makes tunable filters useful is that they provide high performance in a single package. Tunable filters can be offered to cover frequencies as low as 800 KHz or as high as 3 GHz.
  2. High-Power Ceramic Diplexers (Surface-Mount)
    In many cases, identification friend or foe (IFF) systems require diplexers to combine transmit and receive channels onto a single antenna. K&L Microwave’s 9DLX0-1030-1090/X8 is used on the interrogator, transmitting at 1030 MHz. The 9DLX0-1090-1030/X8 is for use in the transponder. Both parts are rated to handle 800 watts of peak power and can be used in military airborne and ground applications.
  3. 15G Diplexer: JDWDF148152U2

    This diplexer has an RX frequency range of 15.12-15.35 GHz, and a TX range of 14.7-14.93 GHz. Additional specifications include 230 MHz -1dB BW, <1.0dB I.L, >50dB isolation, >20dB return loss, <5ns group delay ripple, an SMA-female connection, and 50Ω impedance. The JDWDF148152U2 15G Diplexer weighs 220g and has a silver-plated surface treatment. Download the datasheet for additional information.

  4. WiMAX/WiFi Low Cost Diplexer
    Microlab/FXR, a wholly owned subsidiary of Wireless Telecom Group, Inc., provides a low cost Diplexer, to separate or combine all the cellular wireless frequency bands from the WiMAX and WiFi bands above 3 GHz.
  5. CDMA 450 Cavity Duplexer -- CD7004
    Anatech would like to introduce their products used for wireless communication and to increase frequency in radio communication. CD7004 is a High Performance Cavity Duplexer with Band 1 at 450-454.8 MHz, Band 2 at 460-464.8 MHz, Insertion loss of 1.5dB max, and rejection of > 85dB in Band 2 and >95dB in Band 1. This Duplexer is built in a package size of 287 x 226 x 65 mm, and is used in CDMA 450 Base stations.
  6. FTTP Cable Diplexer
    The FTTP Cable Diplexer uses LC high pass / low pass construction along with delay equalization to provide a clean method of inserting and removing broadband digital service from cable systems. The delay equalizer assists in providing a low distortion path for the digital signal. High volume, inexpensive construction is achieved by casting the housing with connectors molded into a single assembly. Further price reduction is achieved by an internal design which lends itself to pick and place construction...
