LC Bandpass Filters & Duplexers/Diplexers
Anatech Electronics manufactures standard and custom LC Bandpass filters and Duplexers/Diplexers from 0.1 MHz – 20 GHz.
380 To 385 MHz, 390 To 395 MHz Cavity Duplexer -- CD7000
Anatech Electronics introduces a high performance 380-385/390-395 MHz Cavity Duplexer used in T-GSM-380, Aerospace, and UHF applications. The uplink and downlink bands provide a low passband loss of < 1.2dB, and a high isolation of > 80dB. This Duplexer is capable of handling upto 100W of average power, and can withstand extreme weather conditions. A weatherproof version is also available.
AMPS Band Isolation Duplexer
Narda West’s AMPS Band High Isolation Duplexer provides highly selective receive/transmit combining
Diplexers/Multiplexers with Reduced Prototyping
Diplexers and multiplexers are used to either separate or combine two different frequencies that are similar in range to one another. While bandpass filters can also be used to combine and separate signals, they’re only ideal for use with frequencies that are far apart from one another.
Trans Tech, Inc. offers a new, GPS diplexer for systems utilizing both L1 (1575 MHz) and L2 (1227 MHz).
Tunable Filters And Bandpass/Bandstop Diplexers - BT Series
K&L Microwave’s tunable filters and bandpass/bandstop diplexers are usually used in test and measurement applications. Diplexers feature broadband matching at the common port, low insertion loss, and high isolation. Tunable filters are useful because they provide high performance in a single package. They can also be offered to cover frequencies as low as 800 KHz or as high as 3 GHz.
LTE B3/B7 BAW Diplexer (75 MHz/70 MHz): QPQ1237
Qorvo’s QPQ1237 is a high performance bulk acoustic wave (BAW) Diplexer specifically designed for Band 3 uplink and Band 7 uplink applications. Features include low insertion loss, high rejection, high attenuation, and a RoHS compliant 3.00 mm x 3.00 mm x 0.91 mm surface mount packaging.
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.
