N2 - Novel SAW antenna duplexers at 000 MHz and 1.884 GHz are presented. Each of the front-ends consists of a transmitter path containing a SAW Alter for noise suppression, a receiver path containing SAW filters and low noise amplifiers, and a duplexing circuit. For the 000 MHz FDMA mobile radio system the SAW Alters must provide both filtering and diverging. The selectivity of the front-end has been enhanced by a sophisticated design of the microstrip antenna terminal. For the European TDMA cordless telephone system the SAW filters provide preselection and noise reduction. Pin-diode switching is used for time multiplexing. The transmitter path consists of three GaAs-FET low noise driver amplifiers and the SAW filter. The selectivity of the receiver is enhanced by a stripline filter. The feasibility of the combination of SAW and microstrip technologies for the development of low-cost mobile radio units is demonstrated. Design, fabrication and performance of SAW microstrip front-ends in the low GHz range are reported.
