VWA-10-PSMX-21-21-43
Clock Generator with
integrated Phase Shifter
@ 21.5
GHz and 43GHz
Description
The
VWA-10-PSMX-21-21-43
is a clock speed
doubler with phase shifter for high speed transmission
at 43Gbps
.
The
PSMX
module integrates two similar phase shifter
and multiplier blocks in parallel, offering two outputs at
the same frequency with adjustable relative phase.
The second multiplied (and phased) frequency is split
into two paths; one is followed by a frequency doubler.
All the outputs are filtered by a band pass filter; specific
frequency plan can be designed by selecting
appropriate filters.
With an input frequency in the 10,7GHz window, the
PSMX
delivers two 21,5GHz signals and one 43Ghz
signal. All the output signals are phase shifted with
regards to the input, the second 21,5GHz and the
43
GHz signal being phase shifted with regards to the
first 21,5GHz output signal.
The phase shifters are digitally controlled with a 6 bits
command.
