Abstract: | In this work, the determination of receiver selectivity and transmit frequency using a common resonator is presented for a 5.3 GHz transceiver employing a time division duplex, on-off keyed modulation format. The microstrip circuit is fabricated on Rogers RO4003(R) , a high frequency laminate. In receive mode, a 3 dB passband of 35 MHz and a small-signal gain of 26 dB has been achieved. In transmit mode, an output power of +7 dBm for the fundamental, -15.0 dBm for the second harmonic, -18.0 dBm for the third harmonic, and -35.0 dBm for the fourth harmonic has been achieved |
