MtronPTI offers the new high power LC diplexer assembly for a variety of applications, including avionics, electronic warfare, space, and satellite communications. With high power, better isolation/RF shielding, and low insertion loss, these diplexers reduce the overall mechanical footprint, and improved electrical performance and power handling.

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.
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.

Traditional 6 to 42 GHz microwave bands are becoming crowded with rapidly growing mobile backhaul data streams. MtronPTI’s E-Band Microwave Diplexer enables gigabit-per-second data rates in backhaul, data consolidation and enterprise direct connect applications.

The Avago ACMD-7606 is a highly miniaturized duplexer designed for use in UMTS Band 8 (880 – 915 MHz UL, 925 – 960 MHz DL) handsets and mobile data terminals.
Microlab/FXR, a wholly owned subsidiary of Wireless Telecom Group, Inc., recently announced a new far smaller, pre-tuned Diplexer, designed to separate and combine low and high wireless frequency bands with only 0.2 dB loss.
