Specifications for Artemis-I, 4 GHz - 15 GHz synthesizer
Preliminary, 10/29/2023
Designed by: Joe Haas, KE0FF
PLL: TI LMX2594HAT, 10 MHz - 15 GHz PLL, on-board lock LED indicator
Buffer: PMA2-183LN+, 4-18 GHz, +14dBm IP1
DC Power: +5Vdc, 400mA
NOTE: Board requires a heatshink/thermal pad solution
REF: Solder-selectable jumper/capacitor
EXT REF connection: SMA, 0.2 - 2.0 Vpp, 5 MHz (min) - 1400 MHz (max)
INT REF: 25MHz, EXC-TX053-S3-33-250-BN-TR
TTL UART cmd I/O: 3.3V logic, 115200 baud, n81
Control MCU: ATTINY-3217 (uses Atmel 1-wire UPDI programming connection)
RF Out (preliminary), SMA:
4GHz +14dBm
8GHz +14dBm phase noise = -80 dBm/Hz
11GHz +12dBm
13GHz +10dBm
PLL programming allows for adjustment of the output level in 32 steps.
