摘要: A microstrip multiplexer for broadband system applications from 10 to 21 GHz has been developed. The consists of four bandpass filters with center passband frequencies at 10, 12, 19, and GHz. efficiently suppresses the parasitic passbands 10- 12-GHz balances phase relationship among channels. method improving rejection devised. Measured results show that is more than 38 dB. insertion losses are 1.81, 1.90, 2.88, 2.51 dB 10.3, 12.25, 19.4, 21.285 GHz, respectively. out-of-band isolation 32 all these frequencies. This in communication transceiver systems dual-channel receiver (12 GHz) transmitter (10 19 GHz). © 2001 John Wiley & Sons, Inc. Int J RF Microwave CAE 11: 48–54, 2001.
