Description
Summary:[...]both of base station and end-user terminal have to implement dynamic communication chains capable of supporting multi-frequency that implied by Software defined radio (SDR). Due to the latest impositions towards the development and technology of multi-purpose RF front-ends [4], which can support multiple services at the same time such as global system for mobility (GSM) and code division multiple access (CDMA) mobile cell phone services at 0.9/1.8 GHz, or IEEE 802.11a/b/g wireless local area network (WLAN) specifications at the 2.4/5.2-GHz bands. Based on [5], multi-band microwave has been designed and comprised of antenna, amplifier and filter. [...]it has been a great interest in designing the multi-band bandpass filters with less complexity, minimal cost and high performance. [...]implementing PIN diode into design to be function as a switch to produce wideband passband when OFF state, while dual-band passband when ON state.
