Distribution, VHF, 1231A


The ptf 1230A(1U)/1231A(2U) GPS L-Band RF Distribution amplifiers provide high performance GPS signal references for laboratory or systems use. In most applications the low noise and signal gain capability of the units will provide users
with a robust GPS signal source for lab or system requirements.
The ptf 1230A/1231A uses individually buffered output stages and insures maximum isolation between the individual outputs. The ptf 1231A offers 12 outputs. Options are available for a 2U/3.5” version (ptf 1230A) with 24 outputs.
Isolation from output to output is >-40 dB. The input also offers DCV for biasing an active antenna
