In this paper, a compact and high isolation microstrip
diplexer for broadband and WLAN [28, 29] application is designed through the combination of two BPFs without the extra junction matching network.
DESIGN OF
DIPLEXER WITH ROTATIONALLY SYMMETRIC STRUCTURE
The structure and the optimized S-parameters for the compact broadband polarizing
diplexer is shown in Figs.
JMD's new patent pending technology provides the RF industry with a platform for embedding RF passives (RF filters,
diplexer, baluns, etc.) to create integrated passive devices (IPD) and RF module substrates.
The synthesis of the
diplexer is carried out in a normalized frequency domain [OMEGA], defined by low-pass to bandpass frequency transformation as:
Each
diplexer is made up of a low pass filter and a bandpass filter, as shown in the schematic of Figure 10.
In addition, compact filters with higher selectivity and lower insertion loss are required in many applications, i.e., the
diplexer and multiplexer.
This mixer was composed of a hairpin
diplexer, an open stub, and a low-pass filter.
The model DP-1149 is a lumped construction
diplexer. The low frequency port has [less than or equal to] 1 dB insertion loss from DC to 600 MHz, and the high frequency port has [less than or equal to] 1 dB insertion loss from 1000 to 3000 MHz.
