Abstract :
In this paper, a T/R front-end based on Automatic Dependent Surveillance Broad-cast (ADS-B) is proposed. The transmitter front-end with ASK/BPSK modulators and the receiver are installed in two different metal boxes. Experimental results of the front-end verify that the phase noise of the PLL module is lower than -90dBc/Hz at 10KHz offset from carrier of 1090MHz, and the peak output pulse power of the transmitter is more than 51dBm. And the noise figure of receiver measured is lower than 2.5dB. The overall power consumption of the PLL module, modulators and the power amplifier module is about 4.35W.
