The settable output power range is from -5 to +20 dBm. The module has a mili-Hz frequency resolution uses a high-stability internal reference.
The internal reference can be phase-locked to a user-settable external reference. For highest phase coherence, multiple APSYN140 can be cascaded with just one master reference clock.
Phase noise is an important parameter for the performance of a radar system. Most radars employ pulse modulation, and the velocity of the target is derived by detecting the Doppler shift of the radar’s reflected signal relative to the frequency of the transmitter. The transmitter’s own phase noise strongly affects the resolution and accuracy of this measurement, limiting the detection threshold and accuracy of the radar. Therefore, the phase noise of pulsed signals has become an increasingly important measurement.
