Receiver for 1090 MHz ADS-B extended squitter signals
(Automatic Dependent Surveillance - Broadcast, 1090 ES) for air traffic control

The receiver (RF front end & demodulator) processes and demodulates ADS-B Mode-S extended squitter signals (1090 ES) at 1090 MHz. The demodulated squitter signal is available analog in the voltage range from 0 − 2 V for post processing.
To generate an ADS-B testsignal, the receiver has an oscillator integrated. The power of the test oscillator can be varied in four steps, OOK modulation of the 1090 MHz CW signal with test data is available using an external control input.
