Diplexers & Duplexers Products and Services

  1. Ultra Compact L/S Band Filter Diplexer for UAV Communication
    11/13/2013

    The MtronPTI LF9422 L/S Band LC Filter Diplexer is custom designed for small form factor UAV-ISR platforms. Unlike open frame designs, the 1” x 1” wash-proof surface mount package is sealed, allowing automated assembly with no drift after board cleaning.

  2. High-Power Ceramic Diplexers (Surface-Mount)
    6/22/2009
    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. WCS/MMDS Air Cavity Diplexer
    2/23/2006

    This diplexer uses TE Mode waveguide puck resonators to achieve narrowband filters of less than 0.25% bandwidth yet still provide a pass band loss on the order of < 1.5 dB. In addition to the low loss provided by the high Q ceramic resonators, cross coupling is used to achieve very deep rejection of 75 dBc at a 4:1 shape factor. This device also incorporates a sampling coupler and is available in both diplexer and double band pass configurations in frequency ranges of 2250 MHz to 2800 MHz...

  5. WiMax Duplexer
    2/1/2012

    This cavity duplexer for WiMax applications features a small form factor, low insertion loss, high channel selectivity, high isolation, with both custom and standard designs available. Its low channel center frequency runs from 3400 to 3500 MHz, and its high channel center frequency runs from 3500 to 3600 MHz. This WiMax Duplexer’s operating temperature runs from -40 °C to +90 °C, has SMA female connectors, has 100 MHz channel separation, 40MHz channel bandwidth, 1.5 dB max passband insertion loss, and 16 dB min passband return loss.

  6. UMTS Band 2 Duplexer: ACMD-7407
    12/3/2009
    The Avago ACMD-7407 are highly miniaturized duplexers designed for use in UMTS Band 2 handsets and mobile data terminals.
  7. 1905 To 1910/1985 To 1990 MHz Cavity Duplexer -- CD7029
    2/20/2009
    Our 1905-1910/1985-1900 MHz Cavity Duplexer covering a 10 MHz Bandwidth in the PCS bands provides a low insertion loss of 1.4dB max, and isolation of 30dB min. The Duplexer is typically used in PCS base stations, sub-systems, and can be tuned to different center frequencies within the PCS band.
  8. 4 Pole GPS Diplexer
    2/23/2006
    The GPS Diplexer shown here is one of the many variations of GPS diplexers ComNav has available. The ceramic construction filter provides a temperature stable, low loss device which can with stand harsh environments at a low cost. Numerous other types are available with smaller size and /or higher isolation for different GPS applications...
  9. 1940 To 1960/2130 To 2150 MHz Cavity Duplexer -- AD1950-2140D213
    2/19/2009
    Anatech introduces a Narrow Band Cavity Duplexer with a 20 MHz Bandwidth in the WCDMA uplink, and downlink bands, a low Insertion loss of 0.8dB max, and an isolation of 90dB. The Duplexer is used in 3G Base stations and repeater applications. Other sub bands within the WCDMA frequency range are available.
  10. RF Compact LC Diplexer
    7/23/2008
    This small footprint diplxer is designed for the DC-2000MHz band. It features Lowpass rejections of 60 dB minimum from 1200 - 2000 MHz and highpass rejections of 60 dB minimum from DC - 800 MHz.
