The Well Tempered Master Clock Frequency doubler

24.576 MHz to 49.152 MHz Frequency doubler

The TWTMC-DBM duplicates the input frequency. It’s a state of the art device because the phase noise added for each duplication is exactly 6dB (even less very close to the carrier) as expected from the theory. It can be used with base oscillators from 5.6448 MHz up to 24.576 MHz to get the output up to 98.304 MHz.


Base Oscillator type: any

Base Oscillator Frequencies: 5.6448 MHz, 6.144 MHz, 11.2896 MHz, 12.288 MHz, 22.5792 MHz, 24.576 MHz

Output: 50 Ohm sine wave (+10 dBm to +15 dBm)

Output Frequencies: base oscillator frequency x 2 or x 4 (series of 2) up to 98.304 MHz

Board size: 99mm x 75mm (excluding SMA connectors)

Power supply: 12-24 Vdc 30 mA

Suitable box: Hammond 1455J1201 (Mouser part 546-1455J1201)

Board options: finished and semi-finished

Note: max 2 doublers in series, supplied without box
