The ptf 1203C Broadband RF Distribution amplifier provides high performance frequency references for laboratory or system use.
The ptf 1203C uses two stages of input signal buffering to distribute the input signal to 12 separate outputs, and insure maximum isolation between individual output signals.
In most applications the phase noise capibility of the ptf 1203C will outperform the input signal performance to such a degree that no additive phase noise will be noticeable on the outputs.
Isolation output to output is >100 dB and harmonics are <-40 dB.

• Input Frequencies 900kHz to 50MHz
• 12 Broadband Outputs
• Low Additive Phase Noise
• Isolation (>100dB typical)
• Low Cost
• Convenient 1U, 19″ rack mount package
