10GHz and 24 GHz Beacons<\/p>\n

10 GHz beacon set-up<\/p>\n

<\/a><\/p>\n

This consists of a pulse modulated 1152 MHz LO source, with a 96 MHz xtal as start frequency, an amplifier with BFR96,\u00a0 2 * BFQ34\u00a0 and a SRD multiplier.
\nA 2 pole bandpass filter on 10368 MHz and a 30 cm parabolic dish with a dipole feed completes the beacon.<\/p>\n

Detail of the experimental beacon<\/p>\n

Overview of the 24 GHz beacon set-up.
\nThe beacon is build with DMC surplus RF parts. An DRO locked with a PLL on 23.7 GHz is mixed with a pulse modulated LO around 348 MHz to make a frequency in the 24048 GHz band.
\nThis signal is filtered and amplified to a level of 100 mW and terminated with an isolator. The antenna is a 30 cm parabolic dish with a dipole feed.<\/p>\n
