Reference/Synthesis Loop Description
A28 YIG Oscillator (YO)
The YIG oscillator output frequency (3.2 to 10 GHz) is controlled by the amount of current through
the main and FM coils. The main coil is used to set the frequency, and for FM ≤230 Hz. The FM coil
is used for FM rates >230 Hz.
A29 20 GHz Doubler
The A29 Doubler provides:
• a thru path for output frequencies from 3.2 to 10 GHz
• two internal couplers that provide a 3.2 to 10 GHz signal to both the A6 Frac–N for phase locking
during sweep operation, and to generate frequencies ≤3.2 GHz; and the A5 Sampler to provide
the feedback needed for fine tune correction in CW mode
• a doubler path to generate frequencies from 10 to 20 GHz
• RF signal amplification and filtering
